Shift Indicator using Arduino Nano

Last night I watched some Youtube video's on the Arduino chips and boards, and it looks pretty interesting.
I'm already fairly confident I could make a rev limiter easy enough using this tech to block the signal from the distributor to the ECU at a given RPM.
It also looks like one could make it RPM adjustable within the cabin and have a lit LCD screen showing the limit it is set at.
(Or to switch from white light to red at a certain RPM) :D

Now I see why Kit suggested it in the thread about dash lights changing at a set RPM.

The amount of hardware available is pretty impressive also.
Light sensors
sound sensors
Gyro's
LCD and LED panels
Stepping motors
servo's



All kinds of cool things.
