LED stopped working

posted Apr 29, 2017 10:09:44 by MoniAmnah
Hi
I was playing with the lightswitch example, changing the code and trying different things. when I uplaoded a code I heard "MOVI booting" 3 or 4 times then it stopped working even though it worked perfectly before. I tried unplug the power and replug it but it's not working at all.
I am using the mega2560 board.

Sorry to hear that!

What power source are you using?
This typically happens when you use a battery or the USB port for power.

A 9v battery.
What should I do to make it work?

Have you tried a fresh one? 9V batteries go out quickly leading to the symptoms you describe.
