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.

Keywords: Arduino/AVR board, PWM, DC motor, IR based speed monitoring using interrupt, C# etc…
