# Twitch Plays Plotter

A javascript based project with which you can control a pen plotter through the chat of a Twitch livestream.

## Setup
The channel you connect to is specified with the following lines. No authentication is needed, if you're only reading from the chat.
```javascript
const client = new tmi.Client({
    channels: ['twitchplaysplotter']
});
```

The communicative channel with the plotter might depend on your specific plotter and the port it is connected to. This is specified with the following lines:
```javascript
const port = new SerialPort({
    path: '/dev/ttyUSB0',
    baudRate: 9600,
})
```


## Supported commands
The tale of the untested bit of javascript:

the commands are right now
- lb and anything you type after will be plotted as Text
- init
- pu
- pd
- up (move up by {distance})
- down (move down by {distance})
- right (move right by {distance})
- left (move left by {distance})
- rectangle (draw a rectangle with the size of {distance})
- circle (draw a rectangle with the size of {distance})
- set the value for distance

Also, there is the start of some state tracking and clamping to prevent the plotter from getting stuck. But again, untested.
