I am using the Cytron MD10C driver board to power a 12V DC fan using a PWM signal from an Arduino UNO. I am feeding in 12V from an external power supply and I don’t know why at 100% PWM, the motor output terminals get only 4.74V. I am expecting 12V. What is wrong with this picture?
Hi @ScottM and welcome to our forum.
Can we see some pictures of the actual wiring?
Did you buy controller from RobotShop?
Thank you.
I figured it out. i was sending a value of 100 for PWM, not remembering that 255 is the max value.
