How we can calculate rpm of DC motor with the help of ir sensor and ardino
Answers
Heyya buddy :-)
Your question is -
How to measure rpm of dc motor using Arduino?
Well here's your answer:
Arduino can generate PWM on its analog output pin and when it is applied to DC motor, its speed varies. So it is very simple and easy task. To measure RPM, opto-interrupt sensor MOC7811 is used. When motor completes 1 revolution, the sensor generates 1 pulse and such pulses are calculated by arduino to calculate RPM.
Hope it helps.
