So, a year or so back, i just got a new arduino and hooked it up with the following digram,http://i38.tinypic.com/2yzcyf5.jpg
Back then, my electronics knowledge was limited, the mosfet being a IRF540 with a 100Ohm resistor (with the wrong pinout, lol).
Not surprisingly it did not work because the pin out was incorrect
So, i immediately disconnected the circuit but now the arduino does not work, i cannot upload any code to it.
Is there anyway to fix this?
