We're going to use a combination of the Adafruit IO Client Library and Adafruit's CircuitPython to control a Raspberry Pi over Adafruit IO. 


1 x Raspberry Pi 3 - Model B+
The Raspberry Pi is a small linux board compatible with Adafruit IO projects.

If you're following along with a Raspberry Pi, we use the T-Cobbler Plus for the IO Basics Projects. This add-on prototyping board lets you easily connect a Raspberry Pi (Raspberry Pi Model Zero, A+, B+, Pi 2,Pi 3) to a solderless breadboard:

1 x Assembled Pi T-Cobbler Plus
GPIO Breakout - Pi A+, B+, Pi 2, Pi 3, Zero
1 x Green LED
Diffused Green 5mm LED
1 x Jumper Wires
Breadboarding wire bundle.


You'll need to make the following connections:

  • Pi GND to LED Cathode (short LED leg).
  • Pi Pin 5 to one leg of the 560 ohm resistor.
  • LED Anode (long LED legto the other leg of the 560 ohm resistor.
    • note: resistors are not polarized, so the 560 ohm resistor can be connected to the circuit in either direction.
