The LED box is used as a showpiece for visualizing live MEA/neural data from the NTNU Cyborg. The box is a cube of opal acrylic plates containing 240 individually controlled ws2812b RGB-LEDs controlled by an Arduino Mega.
Using FastLED library to control ws2812b LEDs.
Connecting the Arduino Mega to the ws2812b LED strip:
Powering the Arduino using a 5V power supply:
