The concept:
Read keystrokes over serial, parse them into their binary ASCII values, and light up corresponding LEDs.

The Build:
Arduino ProMicro has 8 LEDs connected to 8 pins (2-9) through 10K current limiting resistors, soldered onto a perf board. The whole thing is permanently embedded into a 1-piece 3D printed enclosure by pausing the print, placing the circuit inside, printing the top over it, permanently fixing the circuit inside the housing, printed in transparent PETG.
  • 1 × Arduino Pro Micro
  • 8 × LEDs Electronic Components / Misc. Electronic Components
  • 8 × 10K Ohm Resistor
