    RGB LED selectable colour

    I'm happy to assemble a kit if I know what parts I need and someone could do me a simple circuit diagram. :twothumbs Obviously I'd need a lot of these made up, maybe 200-300 so cost is an issue. The cheapest alternative I can think of at the moment would be a capacitive touch sensor PCB...

    RGB LED selectable colour

    Thanks for the link. I can get that for £2.57 here so definitely a contender. Cheaper than the puck lights at £5 a piece. I'll buy one and see how it can be hacked. We used to have 50p shops, but inflation and all that! Now even Poundland has items that are £2, £5 etc.. Thankfully Aliexpress...

    Thanks but what I am ultimately looking for is an LED (with integrated IC) or a RGB SMD LED on a board that I can change the colour of with the press of a single button. The aim is to have multiples of these (100 or 200 in a grid formation) so that you can press them individually and select a...

    RGB LED selectable colour

    Hi, I've joined this forum to ask one question. I've been pulling my hair out trying to find a solution to this for weeks now and Google seemingly has no answers. About 10 years ago, Radioshack sold a 7-colour and blinking LED with three pins and after an initial startup cycle every time you...
