This week we will install all the circuits we've made as PIC Microcontroller circuit, transmitter circuit, receiver circuit, motor driver circuit to the body of the wheelchair.
This is PIC Microcontroller circuit.As you know, we are using PIC 16F877A.For addition we put an LCD to display the direction , forward ,reverse ,left and right .For reverse we put a buzzer so that the user know they are on a reverse mode.
This is motor driver circuit.This circuit will move the wheel. If the user push forward button so both wheel will move forward,for reverse both wheel will move reverse but for left and right there is little difference.If the user push the left button, the left wheel will move reverse and right wheel move forward and vice versa.
For motor driver power supply, we are using (4) AA battery
This is transmitter circuit, this circuit will send the signal to the emitter circuit
Last but least, the emitter circuit and this circuit will receive the signal from the transmitter circuit
