Hi all,
I have been working on a small circuit the last few days which is designed to be an RGB Led Controller.
I am no electronics expert and have been learning as I go, but I've hit a problem with my finished board and can't figure out what is happening..
The circuit was built using the diagram attached, and everything is indentical except I had to use IRFZ44N fets as I could not source IRFZ14 locally..
Now to the problem.. all the leds on the board work (they are just there for testing so you don't have to attach anything to the outputs) but I get very low voltages from the actual outputs - all of them are giving around 0.02v - 0.08v, it should be more like 12v!
I have metered the voltage at the gate of the fet and they are all around 2.02v
Have I done something wrong or has the change of components screwed something up ?
Thanks!
