Hello,
I'm trying to make a ping ball levitator to teach students how PID works.
I have this Sony fan from spare parts and I would like to control it with an Arduino Uno with a motor shield:
I found this example which looks like it uses a similar fan: https://www.hackster.io/DanDoherty/levitate-a-ping-pong-ball-using-arduino-and-simulink-c403c6
My main question is how do I determine what the three wires on this fan mean so that I can control it? (with PWM, MOSFET, or varying the output voltage)
Based on DC motor standards, I believe that the red wire is hot, black is neutral, but I don't know if the white is a PWM input or something else.
Thank you for your help!
