Arduino NeoPixel Skateboard Lights

C/C++
This code would light up the NeoPixels - which can be programmed to any hue or color.
/*
 * Example Library: Arduino NeoPixel
 * Modified by Eben - smartbuilds.io
 * Date: 29.08.20
 * 
 * Description: Adopted Neopixel example libarary for the Electric Skateboard LED lights
 * This example lights up the front and break lights for the LED.
 * Push buttons can be put on Pin 10 and 11 for indicator lights. More info: smartbuilds.io
