This is a simple COM panel for a flight sim. This uses two rotaries, 2x 6 digit 7 segment displays, and 1 arduino nano. 

Parts needed:

2x 6 digit 7 segment display (T1637)

2x Rotary Dials

1x Arduino Nano

8x M3 Brass Knurled nuts

8x M3x6mm Screws

4x M2x10 Screws (I used M2 instead of m3 for the cover due to running out of M2, should be easy to edit and upgrade to M3 if you want)

4x M2 Brass knurled Nuts (I used M2 instead of m3 for the cover due to running out of M2, should be easy to edit and upgrade to M3 if you want)
