I have connected the gripper with a 12v and the signal wire to PWM of the arduino mega 2560.
I ran the sweep program and there was no response from the gripper,
I checked my signal power and it is .5v.
Do I need additional circuit to turn the signal from .5 to 3.3v to make the gripper work ?
Can you share your code and a picture of how you have this wired up?
Oh, I found my problem, the problem was that the arduino wasn’t sharing the same ground with the power source. Thank you for the quick response tho!
Great and thanks for sharing the solution.
