trigger pullup switch with another controller output ? Steve Thu, 06/01/2023 - 00:05

Hi,

I've got an arduino function works by a pullup pin connecting to ground by a switch.

is there a way to do this with the 3.3V output of another controller? (voice recog board)

I don't think I can change the code to work without the pullup

any help appreciated.
