I've got a project that I'd like to use Arduino's for, I'm just checking the validity of my thought process here.
I have 4 sets of LED light banks (each bank of lights has a Red, Orange and Green LED). I want to build a transmitter, which allows me to select a particular bank, and set that bank's LED colour (either Red/Orange/Green, only one colour can be on at a time).
My thinking is this: the transmitter is basically an Arduino Uno with attached battery, in an enclosure. I'm not sure if I want to use switches to switch between the 4 light banks and to select the colour, or an 'LCD button shield' to scroll through the various combinations.
I'm going to use a radio frequency transmitter shield with the Uno. Here's where I'm not entirely sure. Do I need to have additional Arduino modules at each of the light banks, or can I use a dedicated RF PCB receiver? Also, will the transmitter Arduino need to have 12 channel output (1 for each light-colour combination)?
Any suggestions here or alternate ways of doing this would be great!
