Arduino proteus simulation project with code!

In this arduino tutorial we will see a very cool arduino project simulation in proteus , with the code of cource!
This project is a counter of the multiples of 3! very cool and simple arduino project simulation in proteus 8!
In this project we will use a led to indicate if the current number is a multiple of 3, if it is the the yellow LED wil light up!

how to use proteus 8 for arduino simulation
