Hello!
I want to start by saying that I have no experience/education regarding circuitry beyond gradeschool basics. I'm an illustration student making a very basic prototype for a Toy Design class.
I want to make a magic wand toy that can light up in different colours. I was hoping to use a single RGB LED, but three separate coloured LEDs could probably work too. All that matters is that colours can be lit individually OR mixed. Basically I want each colour to be controlled by a button so that you can have any combination of them on at once to produce the colour you want.
I'm a little lost when it comes to resistors and power supply. Do I need seperate resistors for each colour anode of the RGB LED? What kinds do I need? Can these all be hooked up to a couple AAA batteries? I've seen tutorials online for Harry Potter wands, but these all use just 1 plain LED, no resistors at all, and are frightfully vague in their supply lists.
Thank you for helping out a true noob. I don't have a soldering gun or any other machinery since I'm away from home, but I think I can rent a few simple tools from my school if I need to. I doubt a breadboard would work given the shape of the toy I'm making.
