I’m trying to implement an automated parking lot using an 8051. I’m using stepper motors to function as gates at the entrance and the exit of the parking lot that open whenever the IR sensors placed at the entrance/exit detects a vehicle passing by. I’m also keeping a count of the available slots in the lot using the sensors and I’m displaying it using two multiplexed seven segment displays. The code functions flawlessly within simulation tools like proteus but doesn’t work at all upon physical assembly.
I have physically assembled the 7 segment part of the program (the sub routine called disp) which worked properly. I don’t understand why it stops functioning once I integrate the codes for the stepper motors and the IR Sensors.
Here’s the code:
