Installation

Clone this repository and change the following values in config/index.js:

module.exports = {
  options: {
    channels: ['YOUR_TWITCH_CHANNEL'],
  },
}

Also, you can change the LEDs positions in your Raspberry Pi GPIO pines:

{
  devices: [
    { name: 'led0', driver: 'led', pin: 12 }, //GPIO pin #18
    { name: 'led1', driver: 'led', pin: 16 }, //GPIO pin #23
    { name: 'led2', driver: 'led', pin: 18 }, //GPIO pin #24
    { name: 'led3', driver: 'led', pin: 11 }, //GPIO pin #17
    { name: 'led4', driver: 'led', pin: 15 }, //GPIO pin #22
  ]
}

Run the program in your Raspberry. You will need to connect via SSH or using a Keyboard/Monitor plugged in the Raspberry.

I highly recommend to use a upstart service o pm2 service to run the programa inside the Raspberry.

pi@raspberrypi:~$ npm install -g pm2
$ p2m start twitch-chat-raspi-leds/index.js --name 'twitch-leds'

pi@raspberrypi:~$ pm2 start twitch-chat-raspi-leds --name 'twitch-leds'
[PM2] Spawning PM2 daemon with pm2_home=/home/pi/.pm2
[PM2] PM2 Successfully daemonized
[PM2] Starting /home/pi/_test-leds in fork_mode (1 instance)
[PM2] Done.

Usage

In your twitch chat, write down the following command:

> !led 11111

It will turn on the 5 LEDs connected in your Raspberry PI

> !led 0
> !led 00000

It will turn off the all LEDs.

> !led 10001

It will turn on the first and last LED. Play with them!
