DC MOTOR SPEED CONTROL WITH FEEDBACK MONITOR BASED ON C# APPLICATION

Abstract

Precise, cheap control and monitoring the speed of DC motor is ever hot area of work. In the present paper we have attempted to implement speed control and feedback monitoring for a 12 Volt/1000 RPM rated motor. Speed control is done with help of PWM pins on Arduino/AVR board and H-bridge IC L293D. Feedback speed monitoring is based on IR pair based interrupt monitoring. Hence Sensing and calculation part of process is handled by Arduino/AVR board. All of this is implemented with help of PC based user interface developed in C#. In a typical user interface speed control is achieved with help of trackBar and speed monitoring with help of Text window, was we get direct readout of current speed in RPM.
