Can get the Stirrers to work properly with about 5V only if the Stirrers start slowly and then ramp up speed.
Guess we need to do more testing.
Verify that this does this work with 12V with GRD from both 12V source and Arduino tied.
Verified and added 5V power supply until the PWM issues is decided.
It appears the direct 12V is too fast to spin Fans for Stirrers. The PTFE Magnetic Stirrer Mixer Stir Bars get spun to the side of the containers.
Been difficult to find any solution to use PWM from Arduino (UNO R4 wifi) to control fans.
