This code Below is the Perfect Code for controlling Arduino Bots.
REMEMBER : if you know how to do connections then this code is an elixir for you because unlike previous posts i have provided circuit diagram for connections, but this time this code is prepared by me and i made connections through understanding of code itself.
Enjoy!!
