SPEED AND DIRECTION CONTROL OF DC MOTOR USING ANDROID MOBILE APPLICATION

Abstract

Today most widely used systems are wireless because these systems are less in cost and more efficient than wired systems. In wireless systems, we do not use wires so these systems are light in weight and free from line losses i.e. losses due to the current flowing in the wires. Wires are easily affected by environmental conditions, so wired systems are not so good. In wireless systems, the data is transmitted through the Electromagnetic Waves, and these waves are not affected by the environmental conditions. Also, the environment is not affected by these waves. Hence this is an eco-friendly method. Today motors are everywhere. In every industry, motors are playing a great role-someone appliances motors are playing a common role. This project is about the wireless operation of a DC Motor. We are controlling the speed and direction of a DC motor by using the Android Mobile application. To control the direction of the motor we use the H-Bridge operation of the IC motor driver and control the speed of the DC motor by using the PWM technique.
