Hi guys.
I am doing a project that follows:
I want to charge a capacitor through a SCR. This part I already did. Controlling the angle of the SCR I can control how much voltage will be on the capacitor.
I am using the circuit below.
The problem now is to measure this voltage across the capacitor and send it to a uC.
I am trying to do with a voltage divider but this is not working because I getting strange signal on the middle of the voltage divider.
Circuit:

Any advice?
Thanks
