Hi guys,
I am fairly newish to Electronics so this is all a bit alien to me ... but I'm keen to learn so any help would be really appreciated!
I am working on a project - I require a 12 LED array (3-pin, bi-colour). I need to be able to control each LED separately (its colour and its brightness) and am using an Arduino controller.
I will control the brightness of the LED via pulse with modulation as just varying the voltage directly can potentially cause the LED to go into breakdown etc and we don't want that! ^_^ (I do know a fewwww things!).
So, I need a way to connect these LEDs together (its a 3x4 grid) that allows me to control each ones colour and brightness separately via an Arduino controller.
Software wise I think I am ok, I just need to figure out how to design this circuit with the correct connections for the Arduino so it will be basically 'plug and play' once the software is done.
These are the LEDs I am planning on using: https://www.lc-led.com/View/itemNumber/411
I think that is all the information needed, just give me a shout if there is anything else! I'm looking forward to this project but feel a bit like a deer caught in the headlights at the moment.
Thanks
