The Arduino Bit gives you the power to code your littleBits circuits, allowing you to control the way your lights, buttons, motors, sensors, and other Bits interact. You can now easily incorporate programming into your littleBits circuits! It’s everything you know and love about Arduino without the breadboarding, soldering or wiring. Simply plug into your computer, snap together needed Bits, and program away! You focus on the code, we'll cover the electronics.

We’ve also partnered with codebender to let you easily embed code in your invention page and upload it directly - no integrated development environment (IDE) needed!

  • Build and code with our getting started guides
  • Write and share your code using codebender or create using the Arduino™ programming environment
  • Communicate with software (Processing, MaxMSP, Flash etc…)
  • Connect modules with 3 inputs and 3 outputs using our bitSnap™ magnetic connector as well as additional I/O for advanced hardware interaction
  • Access to community support from Arduino AND littleBits
