I want to connect this metal detector
to PIC16F877 analog pin, but don't know hot to do it. On LED there is from 1,5V to 2V voltage and 20mA current, and I need this voltage to be read by PIC16F877.
I need that microcontroller would read voltage from diode and send signals to other microcontroller.
Can anyone helpme?![Crying :cry: :cry:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
