Good evening. I just build it. The reverse action dosn’t work although the led is showing it s ok. My motor is a cooler fan for pc and tried to change the polarity to see if it works reverse but nothing happens. Can you justify me what i do wrong or what dc motor should by to see the results? thank you in advance
