My goal feels simple: Create a 68 V modulated current using and arduino Uno.
I've connected the base of a NPN MOSFET transistor to my arduino. For some reason after I turn everything on my Uno caught on fire and the base lead starting reading 68 volts.
Will the base lead conduct the voltage away from the transistor at a higher voltage?
Do I just need to put a diode between the base and the Uno?
Did I blow out my transistor and now its conducting through all three lines?
Did I wire my transistor incorrectly?
Help, my wife is going to be mad if I burn the house down.
