Android + Bluetooth Based DC Motor Speed Control System with LCD

Android + Bluetooth Based DC Motor Speed Control System with LCD
Product Code: NRD_PROJ_902
Availability: 5
Qty:        

This project used to control a DC Motor Speed and direction with android based mobile phone. The speed of DC motor is directly proportional to the voltage applied across its terminals. Hence, if voltage across motor terminal is varied, then speed can also be varied.

This project uses the above principle to control the speed of the motor by varying the duty cycle of the pulse applied to it (popularly known as PWM control). Remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based touch screen operation.

The project uses Bluetooth device, interfaced to the microcontroller, which are used to control the speed of motor. PWM (Pulse Width Modulation) is generated at the output by the microcontroller as per the program.
