I want to control the output rotation (in deg) for motor/gearbox combination.
I am using a DC motor coupled to a planetary gearbox and a slew drive (datasheets attached). The motor has a Hall pulse sensor (outputs a square wave) which I want to use to control through what angle the motor rotates.
What I would like to do is: The gear-motor output needs to move 1 deg therefore I must provide power to the motor for 200 Hall pulses (or some other arbitrary numbers).
The Hall pulses are at roughly 70 Hz.
I have tried to use the pulseIn() function, but I don't want a pulse duration, I rather want to count the number of logical HIGH's or LOW's directly.
Are there any other functions that can count the Logic state of a digital pin fairly rapidly (I have tried to look for a few hours)?
Thank you!
