boids

This project simulates a flock of 'boids', or digital birds (or fish). Inspired by this Boids lab from Cornell University.

The project was implemented in C for SDL, then translated to work with an Arduino-driven Adafruit 32x32 RGB LED Matrix. See code below for details on each implementation.

Arduino + Adafruit Matrix

I used an Arduino Metro M0 Express paired with an Adafruit 32x32 RGB LED matrix, see their respective sites for setup information.

The result of a simulation of 15 boids with some color dynamics:
