NanoKontrol LEDs

[MrSteve81]

Been worrking on my plans for a super mod of my NanoKontrol for a few months. Basically going to put it in a box about 5 times bigger, arcade button it up and change all the faders into knobs. I want to keep the ability to change scenes as it's part of my mapping I'm planning and I want to keep the visual feedback given by the LEDs.

My question is does anybody know what LEDs I will need to use, as I want to have 4 different colours.

if you want lots of colours, your best best would be RGB led's... they contain red/green/blue leds in one 5mm package... mix the colours and you have plenty of options

Hey DJNecro how does it work with those rgb led's?

Is the color determined by which pins you connect to ?

Thanks

Yeppers!

most rgb leds have 3 discrete leds in one package, all sharing one common lead (can be either the anode or the cathode). Be careful though, as there are types that are marketed as tri-colour leds. and they ARE NOT RGB... they are usualy simple Red/Green leds with an extra lead that connects both the red and the green at the same time (red, green, red+green = tri colour, but not rgb).

So, using the one i linked to as an example: it's a common anode led, so you would connect the anode to +V and each cathode to ground (or a microcontroller [arduino, etc]) through an appropriate series resistor. (google search: led calculator)

technically speaking rgb leds are able to produce 6 colours (red, green, blue, red+green, red+blue, green+blue), however, by using PWM (pulse width modulation -- way outside the scope of this post) you can theoretically make any colour you want...

Cool thanks for the info

Looks extremely cool. I'll certainly put this at the top of things to research in more depth.
