Heads-up RPM gauge using neopixel sticks

[BDub]

technobly/rpmgauge

Summary

• Uses Mode 1 PID 0x0c for RPM, should work on most vehicles!
• Polls and displays faster than my cluster's RPM gauge!!
• Brighter Indicators at 1k,2k,3k,4k,5k,6k,7k
• Needle changes to Magenta when passing SHIFT_POINT_RPM

TODO

• Add a physical brightness trimpot to the setup to control the brightness (Day/Night needs a big difference in output)
• On/off switch for the OBD-II port so I don't have to unplug it
• Make all wires black
• Mount display possibly using blue tack, and mount it a bit closer to the windshield so it's also lower on the "heads-up" display.
• Add a pleasant sounding piezo for the shift point?

Very nice!!!!!!!!

I had the same concept in mind for a road rally computer display. Kudos for getting your project done, and again very nicely!
