Scroll down for code.....

We all know when we were in school, a person was waiting near school bell to make bell ring. He had to come and rang bell in every period. But what about if it can be automated. Yes it is very simple and we can do that with Arduino. So in this tutorial we are going to make automatic school bell system using Arduino.
