I know there’s a lot of information on the site about connecting multiple LEDs to an Arduino, but after reading through I’m still confused. If anybody could explain it to me in really basic terms, that would be great!
I want to connect somewhere between 60 and 100 RGB LEDs to an Arduino, using PWM to control the colour and brightness. I don’t need to be able to control the LEDs individually - they will all be the same colour at the same time.
I’m confused about how to physically connect them up. Presumably I’ll need some sort circuit or chip to drive the LEDs (because there are so many of them and they will draw too much current) and some resistors? And three sets of them, one for each colour channel?
As you can probably see, I’m a complete beginner when it comes to the hardware side of things.
Thanks in advance for your help.
