How to control a MOSFET switch 16 volts with a microcomtroller?
I've tried this circuit but I still end up measuring 8volts of the base of the transistor with the DMM. I do not want to hook it up to the arduino until I know I won't now up the output.
Can someone please tell me what I am doing wrong? Or suggest a better circuit to use?
I am using a p-channel MOSFET FQP27P06
And a NPN transistor 2N3904
RL is only 130mA at 16v.
