PIC 16F877A & L293 motor driver.

what needed to make it live!

1). PIC 16F 877A microcontroller

2). Oscillator 4MHz.

3). Coupling 22pF capacitors.

4). 5 Volt and Vss pin is connected to Ground.

The balancing robot has two DC motors as actuators. In order to drive the motor, an interfacing

circuit between microcontroller and motor is needed because the microcontroller itself is unable

to supply high current to each motor. Typically, the microcontroller it can only source and sink

approximately 25mA from their output pin. Therefore, a motor driver L293B was used to drive

the motor.
