Hi, I'm new in Arduino, but have some basics in electronics and programming. My question is very simple and so I hope the solution. I'm using Arduino Nano 3.0 with ATMega328 on it. I just want a LED to be on forever, with this simple code: int led = 13; void setup() { pinMode(led, OUTPUT); } …

Arduino Nano resets every 30 seconds

If you just want to light a LED, you don't need a microcontroller.
How are you powering this device?
