hi, can anyone help me,
i have 2 arduino nano, the one works really well
but the other one somehow not working... after i tried a few program...
when i plugged in to laptop, nothings happened, but the power led in arduino lights up, and the L led blinking really fast for about 5sec, then blinking slow for about 2sec... and repeated continuously
i've been once powered that arduino with 2A wall charger, does it broke my arduino??
thanks for helping
