***Please don’t forget to remove/detach the remove the yellow jumper cap from the motor driver before uploading the sketch/code. Re-Connect it after the code has been uploaded successfully.

• The programmer is not responding: If you face this error then it may be because of the Motor Driver. Make sure that you have removed or detached the yellow cap of the motor driver before uploading the code & attach it again once you have done uploading.
• The motor is not rotating in the right direction: If you face this issue then you don’t need to modify any code. You just have to Interchange the motor wires. In a simple way, I can say just connect the Motor to the Motor driver
• Not following the light or running before you have applied the light: This will happen when the LDR sensor modules are not calibrated properly. Put lights on the sensor &  Calibrate them by rotating the potentiometer attached with them.
