I'm building a project for my Physical Computing class that involves 4 vibration motors for varied haptic feedback based on serial input via analogRead. I have each coming out of their own pin and assigned to conditionals.
- how do i control the PWM of each individual motor?
- assuming I need an external power source for the motors, do I need to have a diode and transistor in between each motor and the ground?
Thanks in advance - I'm still learning but definitely looking forward to taking Part II next semester!
