Here is my project - creating a wireless link between my motorcycle helmet and an arduino that monitors 3 inputs from the motorcycle (brake,left turn, right turn). I already have the code done and implemented for hardwire, but for convenience I want to go wireless. The arduino is on the bike, and I have a MAX7219 controlling the 8x8 led matrix on the helmet.
The MAX7219 is expecting Data, Clock and Latch. Simply 3 inputs.
So, does anyone know an easy way (I am still a beginner) to make the wires go away?
