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 modules, and program away! You focus on the code, we'll cover the electronics.

  • Build and code with our getting started guides
  • 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

  • Forums
  • Arduino Programming Guides
  • Note: The Arduino At Heart module requires a power module to function [not included]. If you’re a littleBits newbie, we recommend the Arduino Coding Kit to get started. If you already have a littleBits Kit, you’re all set!
