DC Motor Speed and Direction Control Using GSM Electronics Engineering Final Year Project

This project includes GSM (Sim800c) module, which is connected to Arduino through UART interface. 100 r.p.m dc gear motor controlled through SMS. DC gear motor connected to Arduino through L293d H-bridge IC.

WORKING:

User can control Speed and direction of DC motor using request SMS. Request SMS contains speed and direction fields. Dc motor direction changed by reversing its polarity. Dc motor speed changed by varying PWM cycles.  Based on command DC motor adjusted the speed. This information displayed on LCD.
