An Arduino board controls the game, with a shield made from protoboard to connect the components.

By controlling analog circuits digitally, system costs and power consumption can be drastically reduced. Arduino already include on-chip PWM controllers, making this effectuation easy.

[Patrick] was prepping for some future projects he had in mind, for which he will need a simple 2D array of addressable LEDs. While it is certainly possible for him to build his own LED array and c… ...

The Arduino receives this data and can control either a single-color LED or with an RGB LED strip, assign colors to pitch accordingly using pulse-width modulating on each channel (Red, Green, Blue).

At its core, the Arduino is a small, programmable microcontroller board that accepts and stores code from your computer capable of cool outcomes ranging from controlling lights to making music.
