/*
 * This is the Arduino code for 2 push button to push ON and Push OFF 2 relays and 2 AC bulb
 * the output pen 10 is connected to relay 
 * watch video instruction on video https://youtu.be/7CCSRs5bvH0
 * Be carefull working with AC is dangrous. Disconnect from AC power when working and wear protective gloves when touch the AC components.
