RGB LED. (Arduino UNO)

RGB LED connected to pins 6, 5, and 3 for red, green, and blue respectively.

Fritzing diagram: docs/breadboard/led-rgb.fzz

Run this example from the command line with:

bash

node eg/led-rgb-pulse.js

javascript

const temporal = require("temporal");
const { Board, Led } = require("johnny-five");
const board = new Board();

board.on("ready", () => {
  // Initialize the RGB LED
  const led = new Led.RGB([6, 5, 3]);

  // Set color to red
  led.color("#FF0000");

// Stop and turn off the led pulse loop after
  // 10 seconds (shown in ms)
  board.wait(10000, () => {

    // stop() terminates the interval
    // off() shuts the led off
    led.stop().off();
  });
});
