i sell led bars for work-vehicles. inside the car we have a dash with on/of switch, and a 3way switch that activates the left>right option, right>left option, and outside to inside option off the lightbar on the back of the vehicle.
I need a small (1x3inch) PCB with 6 leds in line, a microcontroller , with a 12V power connector, and 3x12v inputs for the led-sequence selection. if the inputs recieve 12v(or3.3/5v from the microcontroller), they must play the programmed sequence, (the same as the lightbar on the back, so the person inside kan visually confirm the setting of the lightbar outside his vieuw).
i have the code for an arduinomini, and if someone could paste a 12>5v regulator, and an arduino-mini + 6 LEDS on a PCB, that would be great, because we could change the code, and therefore the lichtbar sequence. if not re-programmable, also ok.
