How to Make Timer Switches

In this Project, I show you, how to create timer switches for AC load. These switches can be used for Light bulb, water pump, fan etc. in this project i use five push buttons. Four buttons for timer and one for ON/OFF.

When we press first button it switch ON AC load and when we press again, it switch OFF the the AC load. And when we press second button, it switch ON AC load for 30 minutes. When we press third button, it switch ON AC load for 20 minutes. When we press fourth button, it switch ON AC load for 10 minutes and when we press fifth button, it switch ON AC load for 5 minutes. You can change the timer value from the code.
