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.
Wiper Control Circuit
Buttons with the procedure I’ve created three different studies. F1 button is pressed only once to move the wipers are waiting. F2 button is pressed whether the wipers are waiting for this process 3 times. F3 button is pressed, the wipers make this process four times the water sprays at the same time. Simulation of the water jet engine instead I used the relay with his driver. Working PWM PWM signal to the servo movement produced is achieved.
