Micro Macro Keyboard
thingiverse
This is an 8 button Micro keypad. I needed something really small and even though I see a lot of really nice macro keyboard projects. I wanted something very simple and capable of being changed easily. I soldered the 8 button connections to pins 9 through 2 on the Arduino along with the GND wire to GND. I soldered them in descending order so that USB cable will hang away from me. Note this ONLY works with the " Pro Micro ATmega32U4 5V 16MHz ". The Sparkfun Pro Micro ATmega32U4 5V 16MHz will work also. There are extra board installation steps for the Sparkfun board that are on their site. I included the sketch that I used for my project and the .stl models for the case of course.
