Motor controller for anti stress chair

Abstract

Nowadays, society is dependent on automated system to easier their life. One of the automated systems widely used now days is massage chair. Enhanced from the massage chair system is the goal for this project. The Anti-Stress chair is a system that automatically detects the stress level of the user using their heartbeat detected. Besides that, this chair also has a switch to make it function without detect the stress level but by switch on it. The Anti-Stress chair operated using two DC motor interfaced with 8051 microcontroller. DC motor will rotate simultaneously in clockwise or anti-clockwise direction. A LCD was connected to the same 8051 microcontroller to show the motors direction and to give attraction to the user by display ‘Anti Stress Chair’ message when not being used. This project is practical and highly feasible in economic point of view, and has an advantage of running motors of higher ratings. This project gives a reliable, durable, accurate and efficient way of control of a DC motor.
