I have some analog pins connected to each other and when push button is pressed they all go LOW. Is there any problem connecting pins to each other.

 

Like A0 connected A1 then connected to one end of push button

and on other end, Ground is connected.

 

 

Thank you

Hi xmen,

If you connect two pins together to the same input source, they'll both see the same input (whether that's voltage or digital high/low state). And if you set one as an output pin and one as an input pin, the input pin will see the output pin's state.

The main thing to be careful about when connecting pins together is to make sure you don't set both of them as outputs.
