Use 1Sheeld to get notified that your phone is ringing

 

Hi guys, I made a simple system for indicating that your phone is ringing using Arduino Uno and 1Sheeld.

Circuit design

You can find the design on fritzing.
phone-isringing

Arduino sketch

Actually the code is so simple where it’s one line of code to make the whole thing,
the Phone.isRinging() function return the phone ringing state we are saving in the x variable.
