The image says it all. I'm still hard at work on V2. I'm developing in the latest Arduino IDE (1.6.5) so I had to re-do quite a few things for syntax errors. (UGH!!!!!!) Anyways -- look forward to some exciting new stuff. I overhauled the RPM sensing function. It's my goal to incorporate two methods in the menu, hopefully this will resolve any future issues with detecting RPM. We also have a slimmed rotary encoder function, pixel animations, RPM calibration tool, redline adjustment, and (my personal favorite) a DEBUG option -- Now, don't get too excited (fear of over-promising and under-delivering), but it'll be a baby oscilloscope built in! Soon you can visualize your actual RPM signal with serial output so you can graph it in Excel. Boom goes the shift-light.
