AdafruitGFX is a library that is normally used as a wrapper display libraries, but in this video I show a couple of times I used it in ways it probably isn't meant to be used!



---------------------------------
Project 1 - Falling Sand:
---------------------------------



Code: github.com/witnessmenow/Falling-Sand-Matrix


Adafruit Learn guide it's based on: learn.adafruit.com/matrix-led-sand/overview


ESP32 Matrix Shield:



I now have two matrix shields, this is the PxMatrix one, read about the differences there: github.com/witnessmenow/ESP32-i2s-Matrix-Shield/blob/master/FAQ.md#should-i-buy-this-version-or-the-pxmatrix-version



---------------------------------
Project 2 - Virtual Screen:
---------------------------------


My Original Code: github.com/witnessmenow/ESP32-i2s-Matrix-Shield/tree/master/examples/MultiplePanelVirtualScreenPatternPlasma


I2S Library Example: github.com/mrfaptastic/ESP32-RGB64x32MatrixPanel-I2S-DMA/tree/master/examples/ChainedPanels
