Both boards do not accept codes. I tried 3 different ones, PC 2 different cables, downloaded their driver, updated the driver, let windows install the driver automatically, pressed the reset button while loading (seen on a forum), resorted to Arduino Basic Blink example in case was mine code the problem. Same result every time. It's complete rubbish. Both boards have the same problem. Worst of all, I bought them for a school project that was due in two days. Many Thanks.
