    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 USB LiPo Charger (ADA-CHGLIPO)
    Adafruit Micro LiPo - USB LiIon/LiPoly Charger

    Oh so adorable, this is the tiniest little lipo charger, so handy you can keep it any project box! Its also easy to use. Simply plug in the gold plated contacts into any USB port and a 3.7V/4.2V lithium polymer or lithium ion rechargeable battery into the JST plug on the other end. There are two LEDs - one red and one green. While charging, the red LED is lit. When the battery is fully charged and ready for use, the green LED turns on. Seriously, it could not get more easy.

    Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-voltage trickle charge to keep the battery topped-up. The charge current is 100mA by default, so it will work with any size battery and USB port. If you want you can easily change it over to 500mA mode by soldering closed the jumper on the back, for when you'll only be charging batteries with 500mAh size or larger.

    For use with Adafruit LiPoly/LiIon batteries only! Other batteries may have different voltage, chemistry, polarity or pinout.
    • Comes assembled and tested with a free bonus JST cable!
    • 5V input via PCB-style USB connector
    • For charging single Lithium Ion/Lithium Polymer 3.7/4.2v batteries (not for older 3.6/4.1v cells)
    • 100mA charge current, adjustable to 500mA by soldering a jumper closed
    • Free 2-pin JST cable included!

  • Adafruit NeoPixel Ring - 16 x WS2812 5050 RGB LED with Integrated Drivers (ADA-NRING16)

    Adafruit NeoPixel Ring - 16 x WS2812 5050 RGB LEDs (Model #1463)

    Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75" (44.5mm) outer diameter. 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 colour 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 (4-7V works) 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 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.

    Comes as a single ring with 16 individually addressable RGB LEDs assembled and tested.

  • Sewable Light Sensor with Battery Holder (KIT2721)

    This board allows LEDs to be turned on automatically when it is dark. On one side of the board is the coin cell holder, which takes a CR2032 coin cell as well as a small on/off slide switch. On the other side of the board is the light sensor. This design means that it is possible to cut a small hole in the front of the product for the light sensor to detect the light level, but be able to get to the back of the board to change the battery and turn the board off.

    When turned off,any connected LEDs will be off. When turned on the connected LEDs will be off in day light but come on in the dark. There are two sets of pads that can be used to connect LEDs to the board.

    The board measures 44 x 20 x 4.5 mm (excluding the light sensor, which is 2mm high).

  • Adafruit Sewing Needles - Pack of 20 (NEEDLES)
    Adafruit Sewing Needles

    Mighty needles, sew like the wind! This needle set is the only one you'll need for any sort of hand sewing, especially using our conductive thread and wearable electronics parts.

    Each pack contains 20 gold-eye sharps, with eye sizes ranging from #3 (1.75" long) to #9 (1.35" long). The two #3's (the largest) are too large to pass through the sewable coin cell holder but otherwise are easy to use and thread. The four #9's (the smallest) are a little difficult to thread so you may not want to use them with our conductive thread - they'll be easier to use with normal thread however. The remaining 14 needles are perfect for use with our 2-ply stainless conductive thread or stainless conductive thin yarn
