Block Diagram

—How it Function

• —DC motor will connect to the motor driver and the motor driver will directly connect to the pic18f452 microcontroller as output.
• The PIC will control the DC motor by using PWM that can be setting in the programming part.
• —Next output is LED which is the LED act as alarm to the driver, also directly connected to the PIC.
• —Next part is ultrasonic sensor which is directly connected to the PIC as the input.
