Hi all,
May I know if it is possible to measure DC motor speed with only HPS10 please?
Details as follow:
- No tachometer around,
- No opto sensor/other sensor
- No label on the motor, attempt to check speed from the electric toothbrush
- Did a quick check and saw PWM signal but unsure how to interprete that
I am new to this forum, tried a search for similar topic but did not find anything.
Cheers,
