Hi. We're about to create a design project. Just a quick question:
"How do we upload/gather data to an android app (that we're gonna make) when push button/switch is pressed?
Thanks and God bless.
I have no idea on the Android comms side, but the switch part is easy. Just connect the switch to an i/o pin on one side, with pullup resistors enabled, and fround fround? ground 
on the other. Then have an "if" that requires that pin to go low (button pressed) and inside there, do the Android stuff.
