Topic: My Arduino "forgets" a sketch after the turning power supply off. (Read 389 times) previous topic - next topic


So my Arduino UNO R3 Clone does not run the sketch that was uploaded to him after turning power supply off.
It just blinks the L led a few times,waits a bit,blinks again and it repeats.
For example I had the simple blink sketch that worked(it worked even after pressing the restart button),but I stopped working when I unplugged and plugged the USB.
