Hello i bought a few arduino pro minis from ebay. Sense i never used A6 and A7 i thought i give it a try to see if i can do a button action. But i get nothing from them 6 pins here are the boards Here. So no matter what i do i can not get these pins programmed any other analog pins works fine Just not them two. Can someone help me out please.
These are pure input analog pins. But analogRead() should work. Post your code if you still have problems. See here.
Although they are purely analogue pins you could write a function to read them and return HIGH or LOW depending on the value returned so that it could be used in place of digitalRead()
