PIC16F877 Car Wiper Control Circuit
In this article, a system used in cars which will give information on the wiper control. I made the second one PWM circuit simulation engine will run the servo motor and water spray relay is located. Circuit PIC16F877 microcontroller based on the engine version was used in the IRL530N MOSFETs.
