LED - RGB (Common Anode)

Demonstrates use of an RGB LED (common anode) by setting its color to red (#ff0000) and making it blink. Requires RGB LED on pins that support PWM (usually denoted by ~).

Common Anode RGB LED. (Arduino UNO)

RGB LED connected to pins 6, 5, and 3 for red, green, and blue respectively. The common pin is connected to +5v.

Run this example from the command line with:

node eg/led-rgb-anode.js

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

board.on("ready", () => {
  const anode = new Led.RGB({
    pins: {
      red: 6,
      green: 5,
      blue: 3
    },
    isAnode: true
  });

  // Add led to REPL (optional)
  board.repl.inject({ anode });

  // Turn it on and set the initial color
  anode.on();
  anode.color("#FF0000");

  anode.blink(1000);
});
