Bluetooth Based DC Motor Speed and Direction Control Electronics Engineering Final Year Project

This project includes Bluetooth (HC-05) module, which is connected to Arduino through UART interface. L293d connected to Arduino digital pins.

WORKING:

Here DC motor controlled by l293d (H-bridge) IC. DC motor direction change by interchanging signals of digital pins. Speed will be controlled by PWM. This PWM performed through Arduino code. We have Bluetooth customized APP and using this we can control DC motor speed and direction. Motor speed and direction information displaying on 16X2 LCD.
