It works!

I finally tested the numpad.

Unfortunately the Pro Micros I ordered didn't arrive in time for the weekend so I had to take extreme measures: I ripped it from another project.

I added the reset button and some insulating tape for good measure.

Added the Pro Micro.

Added the OLED screen.

Added the switches.

Some glamorous shots.

I'm getting repetitive, am I?

RGB lighting test result: PASS.

OLED screen test result: PASS.

Oh yeah, it also types number BTW.

It's time to write some proper code now...
