PixArt is a 10x10 "screen" made with a NeoPixel-compatible LED string.

This simple screen shows, in order:

• Alphanumeric text
• A Christmas tree with flashing lights
• Fireworks
• Birthday balloons
• "Picture" of a dog

The dog image is read from a PPM P3 10x10 "file".

Hardware required

• Arduino Uno (it will probably work with other variants, but I've only tested it with the Uno)
• WS2812 Individually Addressable LED Strip Light (NeoPixel-compatible) with 100 or more LEDs
• 50W 5V power supply (to drive the LEDs)
• 1000uF capacitor to smooth out the output of the power supply
• Small (220-470 ohm) series resistor - used between the Arduino (pin 2) and the WS2812’s data input
• Wire and solder (to electrically-connect the cut LED strips)
• Wood, cardboard, tape
