I recently found a Arduino Nano laying around on my shelf, and I wanted to do a project with it. My idea was to turn it into a little keypad thing. (Where people normally would use a Teensy) So I snatched up a few switches from my parts bin. I have 1 switch added to the thing for now (GND -> Switch -> D2). However, I do not know how to continue...
I just want to add like 8 buttons or so (up,down,left,right,x,c,COMMA,PERIOD) so I can take a little keypad pad for Stepmania with me in my pocket.
However, when I look on using an Arduino Nano as HID I get 0 usable results. all of them talk about other Arduinos and the Serial monitor.
I thought, maybe somebody here can help me.
Is it possible at all? or should I search for a different project to use this Arduino with?
