Hi, I just bought arduino mega 2560 and found one problem, when I use arduino atmega 2560 16AU 1130 start getting really hot. If I use arduino long time atmega just burn. What should I do?
If you mean that the microcontroller chip is getting hot, I can think of a few likely causes:
You have one or more of the I/O pins shorted to ground or to Vcc. This could happen if you have wired it up incorrectly, or if it is standing on a metallic surface.
You are trying to drive too heavy a load from one or more output pins.
You are feeding more than 5 volts into the +5v pin, or a negative voltage into the +5v pin.
