I've had the idea for a while now:
An Arduino-based bicycle control system. It would control blinkers, lights, and possibly a couple other things, such as a speedometer.
The bicycle itself is a blue K2 (I believe model 500), and it''s in need of a few minor repairs. Other than that, it currently works, and it hits ~30 like a charm.
The Arduino itself will be in a waterproof case. It will be velcroed underneath the seat, as that's a secure location for it. LEDs will be extensively used in this.
