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);
});
