Built around the 328P, this customizable shift-light is an inexpensive alternative to professional models that cost hundreds more. New features added in V2 mean you don't have to mess w/ the code at all - just upload it to your Arduino Uno.
Here's a list of the adjustable settings: brightness, activation rpm, shift rpm, hardware or software RPM frequency sensing, signal conditioning, engine size calibration, number of LEDs, segmentation and colors of the LEDs, EEPROM memory, +10,000 RPM readout,
can you provide the programming code
