Components

• 1 × LED array In my case a 16x16 array of WS2812B RGB leds
• 1 × Spark Core The Spark Core controls the LED directly and acts as a network server listening for connections over WiFi
• 1 × "SparkLED" python scripts The network client connecting to the Spark Core over the network. These scripts streams data to the Spark Core
• 1 × FastLED (library) Awesome library used on the Spark Core to control the timings of the LEDs as well as higher level functions such as setting brightness
• 1 × Logic level shifter The LEDs need +5V and the Spark Core is a 3,3V device,, so we need a fast logic level shifter
