Hi Guys
I have probably misunderstood something here, but I'm a little confused.
I have a 12V LED strip I'm trying to dim using an Arduino as the PWM signal source and a IRF3204 N-channel MOSFET.
I've kept the circuit simple, basically used this as a guide: https://bildr.org/2012/03/rfp30n06le-arduino/
When I measure the PWM output from the Arduino with my oscilloscope i get a nice square wave going from 0 to 5V. However, when I measure on the "12V side" I still get a nice square wave, but it only "drops" from 12V to about 10V, should it not also drop to 0V when the signal from the Arduino is 0V or have I misunderstood something?
I hope my question makes sense and that I have provided enough info.
Thanks in advanced.
Jacob
