HiI am not able to open the program file.Will you please send me the program as text to me.

When i try to upload this program i am facing error..

I am seeing this error message while compiling what to do

Will you please add the diagram of the circuit with a pcb????

RECTIFIERS ARE NOT PRESENT IN THE CIRCUIT?????IF THEY ARE NOT REQUIRED PLEASE PROVIDE THE BATTERY SPECIFICATIONS???

Where did you buy the tyres from????

Which is better PCB or BREADBOARD??????

Why are you using such a big battery?? We need only 2 9v batteries one to power the motors and other to power the arduinoisn't it??I

Will you please send me the links to buy the components.I am in need please ...
