Help!!!!!!!!!!!!!!! [microcontroller wont respond]

my robot’s microcontroller hasd seemed to stop responding,
I downloaded the default code antd the robot is detecting the transmitter, but none of the motors respond. I have redownloaded the master code and still, same thing:( the batteries in both the transmitter and robot are fully charged. I need the problem fixed by monday.

What code are you using, are you using any custom code? and also are what motor ports are you using?

Sometimes a short can stop the controller from working, try unplug any devices plugged into the I/O ports.

Bingo- I had a motor with a short
thank you for your help.
