Need advice and assistance on a project to demonstrate visible light communication using raspberry pi 3 b+.
I have two modules, a transmitter module and a receiver module.
On the transmitter module I need assistance with connecting two 12v LED's to a breadboard and raspberry pi and modulating the intensity of the light through the raspberry pi.
On the receiver end, having a photodiode.
I need to be adviced on getting both the modules working, having the circuits drawn, told what parts are needed, etc.
At the moment I have a MOSFET but I cannot get the 12v LEDs to work.
