so basically tieing the two grounds together? then why not use a single battery for everything, wouldn't that be the same?
I am using about 2.5A for the motor battery.
you are saying that the harmonic going back to the battery will not affect the microcontroller ?
I suppose the harmonics is g0ing back on the ground, therefore affecting all the grounds in the system ?
I dont have 35 years experience like you guys, just trying trying to learn.
