Automotive car body module control using PIC16F877A

In this paper, the automation system deals development of a BCM with features providing automatic control of windshield wipers, automatic control of head lamps, smart window regulators with anti-pinch feature. Developments of these features were accomplished using a PIC micro-controller 16F877A along with components like sensors, actuators, current drivers & signal conditioning circuits. The BCM developed using a single centralized controller stands as an economical solution which also reduces complexities associated with a typical commercially available vehicle Body Control System. The developed automation system is tested on general purpose PCB with DC motors and LED. The LDR used to detect the light to turn on Manual and Auto headlamp mode.
