Police Strobe Light With Scanner Rgb Leds and Arduino

It's not a real flash pattern used by police.

Just a few loops programmed by me to demonstrate some possibilities.

DISCLAIMER:

I AM NOT RESPONSIBLE FOR THE ACTIONS OR CONSEQUENCES REGARDING THIS TUTORIAL.

Use it only indoors and in private property!

It is not permitted to impersonate a police officer!

Find out how to get the scanner rgb leds in my other instructable.

Also possible with normal rgb leds. (I used common anode rgb leds)

I used the same type of scanner leds (from HP printer) as in my other instructable,

so the pinout is still: green, red, blue, common anode (from top to bottem)

If you use other leds, the order can be different!

Resistors:

I don't know the exact specifications of this led,

so I used resistor values slightly higher than probably necessary.

red: 200 Ohm

blue: 150 Ohm

green not used

I used a Arduino Nano here, but it will work equally well with the other Arduino types.
