Find all the code for our five Workshop Projects below.

Project 1 - Blink an LED

var b = require('bonescript');  // Read library

var ledPin = "P9_14";  // Select pin
var state = 1;  // Set LED state
var interval = 200;  // Set interval (in ms)

b.pinMode(ledPin, b.OUTPUT);  // Set pin to output

function toggleLED() {  // Switch LED on or off
   state = state ? 0 : 1;
   b.digitalWrite(ledPin, state);
}

setInterval(toggleLED, interval);  // Call function at set interval

Project 2 - Red Yellow and Green LEDs

var b = require('bonescript');  // Read library

var ledPin1 = "P9_14";  // Select pins
var ledPin2 = "P9_16";  
var ledPin3 = "P8_19";

b.pinMode(ledPin1, b.OUTPUT);  // Enable pins and set to output
b.pinMode(ledPin2, b.OUTPUT);
b.pinMode(ledPin3, b.OUTPUT);

setInterval(random, 300);  // Call function 'random' every 300ms

function random(){  // Define function 'random'
   b.digitalWrite(ledPin1, Math.round(Math.random()));
   b.digitalWrite(ledPin2, Math.round(Math.random()));
   b.digitalWrite(ledPin3, Math.round(Math.random()));
}
