DC Motor Speed Control Using Flex Sensor
Abstract
In industry DC motor is widely uses for speed control and load characteristics, it's easy controllability provide effective and precise output so application of DC motor is large for commercial purpose. Speed control of DC motor is very crucial in application where required speed is precision and correcting signal representing and to operate motor at constant speed, so we used flex sensor which are fulfill all requirements to speed control of DC motor. In this project, to control the speed of DC motor using flex sensor. Microcontroller Atmega328 is used. L293D IC is used to drive the motor which is made up of two H-Bridge. Rectifier circuit is used for power supply to circuit and motor. This paper shows that precise and accurate control of small DC motors can be done efficiently without using costly components and complicated circuit.
