I have tried to drive a usual trimmer by a microcontroller with an NPN transistor but from some reason, it doesn’t work!!!
Here take a look:
My goal is to control this trimmer that is located and connected on another circuit with that microcontroller.
By this arrengment I tried to use the transistor as a switch and decide when I want the current to pass through the trimmer and when I don’t.
But from some annoying reason, it doesn’t happen, it doesn’t work!!!
the way I tried to make it work is just to send “1” logic to the transistor and in that way to cause the transistor to pass the current through the trimmer (to connect the trimmer to the rest of the circuit).
Thanks in advanced,
Have a nice week,
