So I have two diaphragm air pumps that I need to test out and both use DC motors. I need to control the speed of them and the company suggested I use a PWM controller. What I don't know is if I need to build a specific PWM controller based on the specs of each motor. Here are the specs for each motor:
#1 Current Range (mA) 34 mA to 104 mA Motor Voltage 3.3 VDC
#2 Current Range (mA) 50 mA - 675 mA Motor Voltage 12 VDC
Is it possible to build one PWM that would work for both? And can anyone recommend a good circuit diagram for building this? I do have soldering and breadboard layout experience. I just need to find the right diagram as I really don't know how to do the appropriate calculations.
Also, if its easier and more cost effective to just purchase a PWM module I'm fine with that. Although not as much fun, it might just be easier.
Any help would be GREATLY appreciated.
