PIC powered by capacitor for 0,5 second

[Luciano]

This circuit will control a "stop-light" made of LEDs located in the center of the rear-window of a car.

Function of the circuit: when I go on the brakes, all LEDs light-up.

If I go on the brakes a second time:
- more than half a second later (> 0,5s), all LEDs will light-up again;
- less than half a second later (< 0,5s - or, if I go a second time on the brakes within half a second), I will activate a function that makes my LEDs scroll.

Hi Roger,

Not allowed in Switzerland, in case of a car accident you will have a problem.

The police will stop your car immediately and you will have to fix the car and then
go with the car to the "Service des automobile" of the canton where the car is immatriculated.

Best regards,

Luciano
