Description
A drag race style display using Adafruit's seven-segment backpack display (https://www.adafruit.com/product/878).
This display uses the I2C bus, so multiple displays can be controlled using just four wires.
I have included parameterized FreeCad files (I used version 0.19) so you can modify it to fit your needs.
This is part of the in-process construction of my Hot Wheels drag race track (https://www.redlinederby.com/topic/build-journal-western-oregon-raceway/4915).
