I was taking measures from the outputs of an OpAmp when all the sudden measure 5 volts from all pins of the Arduino Mega for no reason. I disconnected the Arduino and loaded the Firmata and test. All the pins are reading high to 1023.. 5 volts are been output for no reason even when I have the Analog Ping to input.

Sketches code are loading and the lights look normal. I did notice the processor chip getting hot.

Is this a sign of a serious damaged to my device?

Is this really a workshop and events question?

If so, can you tell us where the workshop/event will be held?
