Installation

Then install this module that way:

    npm install raspberrypi-soundbox

Usage

const Soundbox = require('raspberrypi-soundbox');
const box = new Soundbox();

let brightness = 15;

box.setLEDs([1,0,0,1,0,1,1,0,0,1,1,0,1,0,0,1])
box.displayMessage('helo');
box.on('keyPressed',(keyId) => {
  box.setLED(keyId,box.getLED(keyId)?0:1)
});
box.on('keyReleased',(keyId) => {
  box.setLED(keyId,box.getLED(keyId)?0:1)
});
box.on('rotate',(delta) => {
  brightness+=delta;
  if (brightness<0) {
    brightness=0;
  } else if(brightness>15) {
    brightness=15;
  }
  box.setBrightness(brightness);
});
box.on('rotaryPressed',() => {
  console.log('rotaryPressed');
});
box.on('rotaryReleased',() => {
  console.log('rotaryReleased');
});

Members (properties)

• volume Volume level

Methods (functions)

• displayMessage(message: string) Displays a message on the LCD screen
• getLED(ledId: int) Returns the state of a specified led
• getLEDs() Returns an array of leds states
