I have two remote LED arrays that I wish to control with an arduino uno connected to my computer. When I ask this question, I am usually told that I should use my cell phone and a blue tooth connection. The blue tooth connection seems sufficient; however, I do not want to use a phone to actuate the signals, but the arduino and my code.
I seek a transmitter/shield (or it might have to be two) for the arduino that can send signals to two different battery powered receivers that each control LED’s.
Please see the attacched image for clarity and thank you very much.
This must be possible?
Thank you in advance,
