I am trying to use an ATTINY85/Ardunio Uno to turn an LED on and listen to a button input. I don't mind if the LED turns on when the button is used.
I am have found this thread from a couple of years ago however it doesn't seem to work at low voltage (3V) due ending up with floating pins due to the forward voltage of the LED. I was wondering if anyone had a soltion or if they could check to see if my solution would be suitable.
