Hi all,
I'm an absolute beginner and in a few weeks I'd like to start making a circuit that can pulse/breath at a selectable frequency at a selectable wavelength/RGB combination (whatever is easier). It will sit in a housing beneath a variety of clear, interchangeable props for a board game (see below)
The first part is "easy" as I've found numerous 555 timer circuit diagrams. My question is can a variable resistor be used to change the frequency? If so, where can it be used?
Secondly, I've looked over the internet for "selectable RGB circuit" and only come up with prebuilt disco things that connect to LED strips. Is there a way to set an RGB LED to a specific wavelength? Is 3 individually coloured LEDs with varied intensities a valid method of colour control? This is either a really smart or incredibly stupid question -.-"
Anywho, materials for the props aren't going to arrive for a few weeks but any help would be appreciated.
Cheers!
