Hey guys, I got this problem. I have 9 fans motors in which i need to send a range of dc signal of 0-10 volts to each one. I had decided to buy a simple signal generator that can do the trick but soon realized that having one signal generator hook up to 9 motors at the same time will not be very accurate. How do I go around to correcting this without buying 9 different signal generators. Thanks in advance.
