LED matrix made touch sensitive with infrared control

Arduino TeamAugust 19th, 2019

If you’d like to integrate touch functionality to your LED project, then tuenhidiy may have just the thing for you

The setup uses 16 pairs of IR emitter and receivers arranged down the length of a bi-color 16×32 matrix to tell when one has inserted a finger or other object into an area. When sensed, it changes the corresponding column on the display from red to green or back again.

An Arduino Mega is used for overall control of the device, along with shift registers and multiplexers/demultiplexers to account for the massive amount of IO needed. 

Code for the build is available on GitHub, and you can see it demonstrated in the video below.
