Example code for littleBits + Tessel.

IMPORTANT NOTE: littleBits talks over 5V; Tessel talks over 3.3. With this setup, you can send signals from Tessel to littleBits, but DO NOT send signals from littleBits to Tessel or you will fry your Tessel.

Connect like this:

If you connect over Tessel's Vin at 5V, you don't need a battery for the littleBits– and vice versa; if you connect a battery, you don't need to power over Tessel.

Things to know about Tessel

  • Tessel communicates with 3.3V.
  • Tessel can be powered over USB from your computer at 5V or over the Vin header. The 'Vin' pin on the GPIO bank matches the input voltage– so 5V if powered from computer USB. Please see Powering Tessel.
  • Tessel's 3.3V PWM pins are pins G4, G5, and G6 on the GPIO bank. Check out the PWM section of the pin API docs for more information.

Things to know about LittleBits

  • LittleBits is powered on 5V
  • All LittleBits modules use 5V PWM to communicate over their signal pins.
  • The middle pin is the signal pin. The side marked GND is ground.
  • I'm using the proto module.
