LED Knight Rider using Arduino and Mini Led Modules

This project is intended to make a bunch of small leds in a row flash back and forth to look like the car on knight rider

In this case the hardware is 8 mini blue LED modules (http://www.usledsupply.com/shop/smd-blue-3528-mini-led-modules.html) running at 12v DC so a Darlington Transistor Array (ULN2803A) is needed and connected to the 8 output pins on the Arduino, it is also fed (-) 12v to the GND pin and all the leds are fed (+) 12v so only the (-) is switched with the Transistor Array the (ULN2803A) is rated at 500mA/Ch and there are 8Ch but we are only driving 2x 20mA leds per channel so there is plenty of power left

i also used a pot so you can change the speed of the effect on the fly without having to reprogram it

What kind of control unit is that ? ?

And can it ne hooked up to any LED strip ? ?

Where would I get something like that ? ?

[usLEDsupply]

we could build one for you just let me know what all you want and how long of a section you need

[elendal]

try tlc5940 to free ports on arduino

[platinum911911]

well I need one at a size of 12cm, and to have controls the same as you do right here

Trippy.

I'll have to try this.
