Hi,I want to measure voltage with pic microcontroller by this circuit and my qustion is
1- is this circuit is safe for microcontroller ?
2- how I can to isolate the output of the circuit v(an) AN1 to the pin of the microcontroller AN1 ?
1- What do you mean "safe".I want to measure voltage with pic microcontroller by this circuit and my qustion is
1- is this circuit is safe for microcontroller ?
2- how I can to isolate the output of the circuit v(an) AN1 to the pin of the microcontroller AN1 ?
Protect it from what?I want to protact the microcontroller
What I meant was, why do you think you need isolation?I refer to Opto-isolator
