I had been fussing with reading it into pin A0 using any values above 3V as high and 0 as low
.
Read the previous post for criteria to test your analog against
But now I'm wondering if I can just read it into a digital pin to simply do a digitalRead to determine high or low.
You could do that. Since we don't know what the signal looks like you have a 50/50 chance of success with that approach
Thoughts?
try both
I'm especially interested in little fussy coding snipets I need to include to make sure I'm not accidentally causing explosions and mass hysteria all over my psyche.
