    Crumble Getting Started Guide

    The Crumble is an easy-to-use programmable controller. It can drive 2 motors forwards and backwards at variable speeds. It has 4 IO (Input/Output) pads which allow connections to switches, LDRs, low power LEDs and so on.

    Basic Connections

    The Crumble has been designed to encourage tinkering, using ‘croc leads’ for quick and simple connections. Pads allow terminal blocks to be fitted or a direct solder connection made, while the larger 4mm holes make an easy target for conductive thread and needle.

    Crumble with croc leads

    The Crumble software runs on PC, Mac and, in the near future, Linux (including the Raspberry Pi). Inspired by MIT Scratch, programs are simply built by snapping blocks together on screen. Sending a program to the Crumble is almost instant, allowing rapid experimentation.

    The Crumble can be extended with digitally controlled full-colour LED, called Sparkles. Additionally, several expansions board (Crumbs) are also in the works.

  • Adafruit NeoPixels v2 - Pack of 4 Flora Smart Neo Pixels 24-Bit RGB LEDs (#1260)

    Adafruit Neo Pixels - Pack of 4, RGB LEDs (Model #1260)


    What's a wearable project without LEDs? Our favorite part of the Flora platform is these tiny smart pixels. Designed specifically for wearables, these updated Flora NeoPixels have ultra-cool technology: these ultra-bright LEDs have a constant-current driver cooked right into the LED package! The pixels are chainable - so you only need 1 pin/wire to control as many LEDs as you like. They're easy to sew, and the chainable design means no crossed threads.

    This is the second version of the Flora NeoPixels, which runs at at 'high speed' 800KHz communication. Unfortunately they are not back-compatible with the chip-on-back 'low speed' (400KHz) Flora NeoPixels. If you have a project that already uses low speed pixels, and you want to attach more pixels to the chain, you will need to purchase version 1's as these are not cross-compatible.

    These pixels have full 24-bit color ability with PWM taken care of by the controller chip. Since the LED is so bright, you need less current/power to get the effects you want. The driver is constant current so its OK if your battery power changes or fluctuates a little.

    Each pixel draws as much as 60mA (all three RGB LEDs on for full brightness white). In theory, the Flora can drive up to 500 pixels at 30 FPS (it will run out of RAM after that). However, after about 10 pixels (or if the distance between pixels is more than an inch or two) the resistance of the thread can affect the power supply. For large quantities of pixels over 10, you may want to consider using stranded core wire or copper braid to provide a "power bus" for the pixels - the current draw will add up fast!

    Each order comes with 4 individually controllable pixels.

  • Adafruit Breadboard-Friendly RGB Smart NeoPixel - Pack of 4 with Headers (#1312)

    Adafruit Breadboard-Friendly NeoPixels - Pack of 4 (Model #1312)

    This is the easiest way possible to add small, bright RGB pixels to your project. We took the same technology from our Flora NeoPixels and made them breadboard friendly, with two rows of 3 x 0.1" spaced header on each side for easy soldering, chaining and breadboarding. These ultra-bright LEDs have a constant-current driver cooked right into the LED package! The pixels are chainable - so you only need 1 pin/wire to control as many LEDs as you like.

    These pixels have full 24-bit color ability with PWM taken care of by the controller chip. Since the LED is so bright, you need less current/power to get the effects you want. The driver is constant current so its OK if your battery power changes or fluctuates a little.

    Each pixel draws as much as 60mA (all three RGB LEDs on for full brightness white). An Arduino can drive up to 500 pixels at 30 FPS (it will run out of RAM after that). Using ribbon cable you can string these up to 6" apart (after that, you might get power droops and data corruption)

    Each order comes with 4 individually controllable pixels. In the photos below we show the pixels with headers soldered on. We include a 40-pin male header strip with each pack of 4

    Check out Adafruit's Arduino library at github which has some example code for driving the pixels at 800KHz

  • Adafruit NeoPixel Matrix 8x8 - 64 RGB LED Pixel Matrix (ADA-NEOMATRIX)

    Adafruit NeoPixel Matrix - 64 RGB LEDs in 8x8 Matrix (Model #1487)

    Put on your sunglasses before wiring up this LED matrix - 64 eye-blistering RGB LEDs adorn the NeoMatrix from Adafruit for a blast of configurable color. Arranged in an 8x8 matrix, each pixel is individually addressable. Only one microcontroller pin is required to control all the LEDs, and you get 24 bit color for each LED.

    Wiring it up is easy: there are two 3-pin connection ports. Solder wires to the input port and provide 5VDC to the +5V and ground pins, then connect the DIN pin to your microcontroller. If you're using our NeoPixel Arduino library, use digital #6. You'll also need to make a common ground from the 5V power supply to the microcontroller/Arduino. Since each LED can draw as much as 60mA (thats up to 3.5 Amps per panel if all LEDs are on bright white!) we suggest our 5V 2A power supply. For most uses, you'll see about 1-2A of current per panel.

    If, say, you need MORE blinky, you can chain these together. For the second shield, connect the DIN connection to the first panel's DOUT. Also connect a ground pin together and power with 5V. There you go! You can chain as many as you'd like although after 4 or more panels you may run low on RAM if you're using an UNO. Watch your power usage too, you may need a 5V 10A power supply for so many of these!

    There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. Adafruit's wonderfully-written Neopixel library for Arduino supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required.

    Adafruit's detailed NeoPixel Uberguide has everything you need to use NeoPixels in any shape and size. Including ready-to-go library & example code for the Arduino UNO/Duemilanove/Diecimila, Flora/Micro/Leonardo, Trinket/Gemma, Arduino Due & Arduino Mega/ADK (all versions)

  • Adafruit NeoPixel Quarter 60 Ring - 15 x WS2812 5050 RGB LED with Integrated Drivers (ADA-QRING15)

    Adafruit NeoPixel Quarter Ring - 15 x WS2812 5050 RGB LEDs (Model #1768)

    The biggest NeoPixel Ring yet! With four of these you can make a huge ring with 60 ultra bright smart LED NeoPixels are arranged in a circle with a 6.2" diameter. Each order comes with just the quarter ring. Four of this item are required to make a large ring. You will have to solder them together as well, so for the full ring of 60 LEDs, buy four and solder them together!

    The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you're ready to rock.

    There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microcontroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. Adafruit's wonderfully-written Neopixel library for Arduino supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required.

    Comes with one quarter ring of 15 x individually addressable RGB LEDs assembled and tested. We recommend you buy four to build the full circle as this is just the 1/4 of the circle.

  • Adafruit 16-Channel PWM / Servo HAT for Raspberry Pi - Mini Kit (ADASERVOHAT)

    Description

    The Raspberry Pi is a wonderful little computer, but one thing it isn't very good at is controlling DC Servo Motors - these motors need very specific and repetitive timing pulses to set the position. Instead of asking the Pi Linux kernel to send these signals, pop on this handy HAT! It adds the capability to control 16 Servos with perfect timing. It can also do PWM up to 1.6 KHz with 12 bit precision, all completely free-running.

    For use with Raspberry Pi Model A+, B+, or Pi 2 can be used with the Model A or B if you use a tall 2x13 header instead of the included 2x20.

    The Adafruit 16-Channel 12-bit PWM/Servo HAT will drive up to 16 servos or PWM outputs over I2C with only 2 pins. The on-board PWM controller will drive all 16 channels simultaneously with no additional Raspberry Pi processing overhead. What's more, you can stack up to 62 of them to control up to 992 servos - all with the same 2 pins!

    Best of all, we even have a Python library you can use, so you'll be up and running instantly, to make your robotic creation com to life. The Adafruit PWM/Servo HAT is the perfect solution for any project that requires a lot of servos or PWM outputs! Please check out this detailed tutorial for lots more information including diagrams, schematics, installation instructions and more

    Each order comes with a Servo HAT, a 2-pin terminal block, four 3x4 headers and a 2x20 socket header. You'll need to do some light through-hole soldering to attach the headers onto the HAT circuit board, but its easy to do with basic soldering tools like a soldering iron and rosin core electronics solder. If you would like to stack multiple HATs onto one Pi, you can also pick up a 2x20 stacking header and a set of right-angle 3x4 headers that should be soldered on instead.

    Please note! This kit does not come with Raspberry Pi, servos, or required 5V power supply

  • Pi-Stop Educational PiStop Traffic Light Add-on for Raspberry Pi (RPI-STOP)

    Introducing the Pi-Stop

    The Pi-Stop is a low cost hardware module designed to allow Raspberry Pi users to take their first steps into interfacing with the real world.

    Designed with the learning in mind, everyone will recognise and identify its familiar elements encouraging their use along-side their own projects.

    See this independent review
     

    Move past the Stop light

    The Pi-Stop is designed to remove many of the common hurdles people are faced with when getting started using hardware with the Raspberry Pi. Often it is difficult to know what components to use and how to connect them, the Pi-Stop makes it simple by plugging directly onto pre-set positions on the Raspberry GPIO connector.

    By plugging the Pi-Stop directly on to the Raspberry Pi GPIO header, no extra cables or wires are needed. Unlike many other add-on boards, they do not block unused GPIO pins, keeping them open for other uses. The Pi-Stop can be fitted in 4 standard locations, allowing up to four Pi-Stops to be controlled independently or combined with other hardware.

    When used with optional stands, they can be used away from the GPIO header and even daisy chained to make up full traffic light sets.

    For more information about the many ways the Pi-Stop is fitted see the Pi-Stop documentation below.

    Prepare to go!

    The Pi-Stop provides a simple stepping stone, between pure screen based programming and using physical hardware to interact with the real world. Components like the Pi-Stop will provide a flexible and non-restrictive way to build understanding through experimenting.

    Since it is only a step away from a bag of components, it also allows the programming of hardware to be introduced, and the electronics involved can be introduced separately, if desired. Allowing the pupils to discover they can control real things, and then again to discover they can also build their own circuits and control them in exactly the same way.

    Often, people are faced with a magic board which they plug in and tell it to do stuff, however it isn't always clear to them why or how it does it. By providing something which they can remove and replace with something (apparently) completely different (- wires, breadboards and LEDs) they will be able to understand the link.

    By keeping the hardware very simple, it allows better understanding of what is happening, and allows space to come up with your own projects and apply the concepts with your own ideas in mind.

    GO Full throttle

    The documentation and guides are openly available for the Pi-Stop for educational use. There will be guides, tutorials and workshop material available all of which can be taken as is [available as PDF format] or adapted to your own needs [available in markdown format].

    It is encouraged that similar materials can be submitted back for others also to share and make use of.

    The materials will demonstrate the concepts, methods and provide the building blocks to explore ideas and take learning further by with creative projects, activities and games.

    High quality module
    High efficiency AT commands, simple for your development.
     
    Important note:  This is a 3.3v module, ensure it is only connected to the 3v lines on your micro-controller, direct 5v will damage the module.
     
    In addition to the 3.3v power supply for the module, 5v TTL data lines also need to shifted to 3.3v. When using the module with a 5V micro-controller, such as a standard Arduino,  ensure to use a level shifter on the URXD pin - a simple resistor-zener level shifter is sufficient. Again, this is to prevent over-voltage.

  • GPIO Breakout Intercept for 40-pin Raspberry Pi PCB (10 pack) (BBBBRKT10)
    40-Pin GPIO Breakout for Raspberry Pi - 10 Pack PCB+GPIO Header Only

    This item is a panel of 10 PCBs with the GPIO connector already soldered on. The additional female and male headers shipped with the single item are not included.

    A great way of accessing those unused GPIO pins even when they're covered by a HAT
    • Suitable for all Raspberry Pi with 40 pin GPIO. Zero, A+, B+, 2B, 3B
    • GPIO header is pre-soldered
    • All pins labelled (Broadcom naming)
    • Solder wires directly to the broken out pins or solder a male header (not included)
    • Uses a low-profile header fitted to the breakout PCB and an extended female header (not included) that you simply push through the holes (see photos)
    • Plug your HAT or other addon board into the pins of the extended header
    • Matte black PCB with gold plated contacts
    Contents:
    • PCB with pre-fitted GPIO header (male header and extended female header NOT included
    • All RoHS compatible and gold-plated
    Part of the Basic Building Blocks range from 4tronix which enables stacking multiple addons. As with all products in the range, the GPIO header is pre-fitted, leaving you to solder the through-hole components.

    NB. Some HATs using low-profile headers may not make as good contact with the header. In that case, you will need to screw the HAT firmly into supporting pillars (not included).

  • Bit:Bot Robot for BBC Micro:Bit (BitBot for MicroBit) (BITBOT)
    Bit:Bot Fully Integrated Robot for the BBC Micro:Bit

    NB. BBC Micro:Bit is NOT included unless specifically selected with the checkbox

    This (almost) ready-assembled robot requires no soldering, no wires and nothing more than a screwdriver to complete it.

    The Bit:Bot fully engages children and adults alike, allowing you to explore and code the BBC Micro:Bit using any of the languages available (not all features are supported in all languages)

    Learn here how to control the Bit:Bot with your Bluetooth phone

     *NEW* There is now a Microsoft PXT package for Bit:Bot (thanks to Sten Roger Sandvik, @stenrs on Twitter). Go to the Advanced tab or the Tools gear icon and select Add Package, then search for BitBot
     

    Check out these features:
    • 2 micro-metal gear motors. Both fully controllable in software, for both speed (0 to 100%) and direction (forward or reverse)
    • Wheels with rubber tyres for maximum grip
    • Really smooth metal ball front caster
    • 12 mini neopixels in 2 sets of 6 along the arms either side. Select any colour for any pixel, produce stunning lighting effects as your Bit:Bot moves around
    • 2 digital line following sensors. Code your own line-following robots and race them to see whose code produces the fastest lap time!
    • 2 analog light sensors (front left and front right) so your Bit:Bot can be programmed to follow a light source such as a torch, or you could code it to go and hide in the darkest place it can find
    • Buzzer, so you can make beeping sounds whenever you want
    • Powered from integrated 3xAA battery holder with on/off switch and blue indicator LED
    • Easily plug your BBC micro:bit in and out using the edge connector
    • Extension port for addition neopixels (such as McRoboFace)
    • Expansion connections at the front for additional sensors (Ultrasonic rangefinder available now, more in development)
    Optionally, you can add an Ultrasonic Distance Sensor (rangefinder) module. The sensor can be either soldered to the module, or connected via a socket. No soldering is required for either version. The socketed version makes it easier to connect a micro-USB lead to the Micro:Bit, but the soldered version is more robust.

    We also have an option for a pen holder that is fitted at the back. This can be plain, or have LEDs on to create a glow ring effect around the pen
