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. 

Parts

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:

Wiring

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 leg) to 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.
