I'm working on an Arduino Uno project that requires 6 digital I/O pins. I've been experiencing problem with false "HIGH" readings during testing. I've narrowed down the problem to the digital I/O pins being unstable.
The pins will read as "HIGH" when touched by hand or when near other electronic components (ie. the jumper wires on my prototyping breadboard).
Now, it will not be handled during it's actual application but it will be in the same enclosure as a 9V battery and I'm uneasy about the false readings.
Has anyone ever experience this issue with an Arduino board? If so, what steps did you take to work around it?
