# RGBIsoGrid

This Arduino sketch drives a string of 49 WS2812 RGB LEDs, arranged

in an isometric grid layout.

One additional LED (it's a 50-LED string) at the far end is unused.

The Arduino is also connected to a button and an analog potentiometer.

The button selects which demo to execute, and the pot controls the

demo.

## Library Usage

This sketch requires the use of the 'FastLED' library.

The library provides all the code to efficiently drive the LED string.

## Hardware Setup

The LED chain is connected to Arduino digital pin 3 (change this in the

code by changing 'DATA_PIN').

There's an analog pot connected to Arduino analog pin 0 for setting

hues, brightness and so on.

The mode selection is done by a push-button switch on Arduino digital

pin 2 ('BUTTON_PIN' in the code).

The button has a pull-up resistor connected, and it grounds the input pin

when pressed.
