Sub : Report on lab 03

Lab 03 was a very intresting lab. From this lab we leant how to use a potientiometer and a js fiddle software to control our led brightness and power

In lab 03 we use two LED's for following pusrpose:

1. To glow both the LED's: For this led we use
2. To glow one LED's while another one fade away
3. To control the brightness of both the LED's using a poteniometer
4. Then we use fiddle to saw our code and make some changes in our code like we get values of potentiometer and a button on screen to turn off and on the LED's.

CODE FOR blinking an led:

var b = require('bonescript');

var leds = ["USR0", "USR1", "USR2", "USR3", "P9_14"];

for(var i in leds) { b.pinMode(leds[i], b.OUTPUT); }

var state = b.LOW; for(var i in leds) { b.digitalWrite(leds[i], state); }

setInterval(toggle, 1000);

function toggle() { if(state == b.LOW) state = b.HIGH; else state = b.LOW; for(var i in leds) { b.digitalWrite(leds[i], state); } }
