I bought a couple of 64x64 LED Matrix displays and used an ESP32 to control the display of images on it.<p>It now makes a cool feature in my room<p><a href="https:&#x2F;&#x2F;github.com&#x2F;bradleeharr&#x2F;Image-Display-LED-Matrix">https:&#x2F;&#x2F;github.com&#x2F;bradleeharr&#x2F;Image-Display-LED-Matrix</a><p><a href="https:&#x2F;&#x2F;github.com&#x2F;bradleeharr&#x2F;Perlin-Noise-LED-Matrix">https:&#x2F;&#x2F;github.com&#x2F;bradleeharr&#x2F;Perlin-Noise-LED-Matrix</a>

Testing circuits I’ve made on a breadboard.<p>I have some addressable LED strips that I want to put on my car and make a stream of hearts and stars as I drive past or overlay my car (for one moment) with an Acura NSX or something like that. I got stuck developing a test framework for it (can’t test it fully in motion) and never figured out a good way to set it up in the car but really I should ‘just do it’.

College senior project - 3dof robotic arm on a vertical gantry system attached to a hydroponic garden. We used 2 arduino’s to control the lighting and gantry. Then one pi onboard the robot for imaging and another for a web user interface.
