First we will create a simple input controller that will let Adafruit IO know what button was pressed. For this project we will be adding buttons to represent each of the possible states to be passed to our output device.
- 0 will represent "OFF"
- 1 for Red
- 2 for Green
- 3 for Blue
There are a few things we will need to get started:
- 1 x HUZZAH ESP8266
- 3 x colored tactile push buttons (Red, Green, and Blue)
- Six 470 Ohms resistors
- Jumper wires
Now let's get started with the wiring.
