  • Arduino Micro (A000053)

    Arduino Micro

    Code: A000053

    The Arduino Micro is a microcontroller board based on the ATmega32u4 (datasheet), developed in conjunction with Adafruit. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard.

    The Micro is similar to the Arduino Leonardo in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. It also has other implications for the behavior of the board; these are detailed on the getting started page.

  • Pi-Lite - Lots of LEDs for the Raspberry Pi (PiLite Red) (CIS-B040)

    Product description

    The Pi Lite is a large LED matrix display for scrolling text and graphics. It's an exciting way to get a Raspberry Pi to do something physical and fun. It's an easy plug in add on, so no soldering or special skills are required.

    The Pi Lite mixes the highly popular Arduino "Lots of LED's" shield by Jimmy Rogers with the world of the Raspberry Pi. Using standard serial communications (@9600bps), it's really simple to send text and graphics to the 126 LED's. The matrix is powered from an ATMega328p processor which means all the processing of driving the 126 LED's is off loaded from the Pi's processor. This frees the Pi's processor and GPIO for other functions.

     

    Video 1: http://youtube.com/watch?v=VpGx1KSqVbM

     

    Video 2: http://youtube.com/watch?v=3MKCH2ytzdQ

    • Fun and practical (perhaps display your emails or tweets in real time, scroll messages that can be seen at a distance)
    • Open source firmware (you can build in extra functions if you desire)
    • Multi function - Scroll text, bargraph, VU meter & graphics (all easy to use by sending just simple text strings)
    • Based on the Jimmy Rogers LOL shield (well tried, tested and supported)
    • 14 x 9 matrix of LEDs (for text or graphics)
    • It's serial so can be used with any TTL micro, radio (eg XRF) or PC interface (for example the popular FTDI cable)
    If you are not yet convinced, we have a Pi-Lite emulator (written in Python), so you can try before you buy.

    Features:

    • On board ATMega328p
    • High quality gold plated PCB
    • 126 Red LEDS (a White version is also available)
    • Data is driven by the Pi serial UART (you may need to setup your serial port, see below docs).
    • Runs at 5 volts off the Pi supply (49ma max)
    • Preloaded software, can be used out of the box to display the following
      • Scrolling Text (speed variable)
      • Bar Graph (vertical 14 bars)
      • VU Meter (horizontal 2 bars)
      • Frame buffer (for graphics and animation)
      • Individual Pixels (turn them on, off or toggle)
    • Pre-built / Plug and Code
    • Ability to install 6 pin ISP or 6 pin FTDI Headers to the ATMega328P for firmware upgrades or your own sketches
    • ATMega328p analog pins are broken onto standard holes (just like the Jimmy Roger shield)
    • I2C from the ATMega328p is available on pins A4 and A5 for daisy chaining of Pi-Lite to create a bigger display
    • Made in the UK

    • Playground for Crumble (Crumble is optional extra)
    • 4 x Connection Cables
    • Traffic Light Gizmo
    • Dial Gizmo
    • Buzzer Gizmo
    • 2 x Flame Gizmos
    • Prototyping Gizmo

    Features:
    • Fittings for your Crumble (Crumble not included, unless selected)
    • Battery holder for 3xAA batteries permanently fitted (batteries not included)
    • Sturdy On/Off switch
    • Blue power indicator LED
    • White LEDs on all 4 inputs to show when active
    • All Crumble Input / Outputs are brought to standard Crumble connectors so you can continue to use existing Crumbs and Sparkles etc.
    • Each new connector includes the signal as well as power and ground
    • Fast and easy to connect

    Other Gizmos - Available now
    Many Gizmos are already available and more are on the way. Each Gizmo connects directly to the Playground with usually one connection cable (Traffic Lights uses 3 cables, one for each colour). As with our Crumbs, the Gizmos are colour coded:
    • Blue - Digital Input (eg. Button)
    • Yellow - Analog Input (eg. Dial)
    • Black - Digital Output (eg. Buzzer)
    • Red - Analog Output (eg. motors)
    • White - Smart pixels ("Sparkles")

    Here is a great video introducing Playground for Crumble

  • PIR Sensor Crumb Digital Input for Crumble Controller (CRPIR)
    PIR Sensor Crumb for Crumble
    (Digital Input Crumb)

    This Crumb is fully compatible with the Crumble Controller and makes it easy to use Croc Clips to show Digital (On and Off) inputs or use them to control LEDs or Motors.

    This Crumb has an infrared sensor module with high sensitivity to changes in IR levels - ie. moving people. You could easily use it for an intruder detector, or challenge the children to reach out and press a Button Crumb before the PIR Crumb detects them (they will have to move very slowly!)

    Crumb Colour Coding:
    Yellow: Analog Input
    Red: Analog Output
    Blue: Digital Input
    Black: Digital Output

  • 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
