Button not working correctly. Static bool, Potentiometer. uno

[miked34]

@gcjr

the input, A1 always be 0V if the button is not pressed. when the button is pressed, an analogRead (A1) would measure the setting of the wiper from 0-5V.

with the above approach, conditional could be executed while the button is pressed (no need for ledflag)

I just realized a potential problem with using the switch and pot in series, if I adjust the pot so the voltage is below 3v the switch will be considered filliped and the lights will stop.

If I attached the pot to 5v pin and A2 , then the switch to 5V and A1 could I still use this if statement above for the button ?

Thanks !
