Is it possible to kill arduino nano with overload?
I wanted to drive a relay with arduino, and I used a BC547 to switch 12V for the relay. But in the relay there was a diode, which sorted out the circuit (thats why I drawed in the wrong orientation)
I know it was a mistake to not use current limiting resistor on Base of the transistor.
Is it possible that this shorted circuit made too much current on the transistor base which killed my arduino?
