Hi again!
Is arduino able to control 4 motors???
I was testing today the mosfets i got... i did not plug in arduino but started with 3v battery in place of arduino and it did not work, well it also can be because i was in a hurry and could make a mistake, but i think i should ask if it should have worked with battery 3v in place of arduino and 9v on the motor as it was on the scheme...
