/****************************************************************************
* This example was developed by the Hackerspace San Salvador to demonstrate
* the simultaneous use of the NeoPixel library and the Bluetooth SoftDevice.
* To compile this example you'll need to add support for the NRF52 based
* following the instructions at:
* https://github.com/sandeepmistry/arduino-nRF5
* Or adding the following URL to the board manager URLs on Arduino preferences:
* https://sandeepmistry.github.io/arduino-nRF5/package_nRF5_boards_index.json
* Then you can install the BLEPeripheral library avaiable at:
* https://github.com/sandeepmistry/arduino-BLEPeripheral
* To test it, compile this example and use the UART module from the nRF
* Toolbox App for Android. Edit the interface and send the characters
* 'a' to 'i' to switch the animation.
* There is a delay because this example blocks the thread of execution but
* the change will be shown after the current animation ends. (This might
* take a couple of seconds)
* For more info write us at: info _at- teubi.co

#define PIN 15 // Pin where NeoPixels are connected
// Declare our NeoPixel strip object:
Adafruit_NeoPixel strip(64, PIN, NEO_GRB + NEO_KHZ800);
// Argument 1 = Number of pixels in NeoPixel strip
// Argument 2 = Arduino pin number (most are valid)
// Argument 3 = Pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
// NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products)
// NEOPIXEL BEST PRACTICES for most reliable operation:
// - Add 1000 uF CAPACITOR between NeoPixel strip's + and - connections.
// - MINIMIZE WIRING LENGTH between microcontroller board and first pixel.
// - NeoPixel strip's DATA-IN should pass through a 300-500 OHM RESISTOR.
// - AVOID connecting NeoPixels on a LIVE CIRCUIT. If you must, ALWAYS
// connect GROUND (-) first, then +, then data.
// - When using a 3.3V microcontroller with a 5V-powered NeoPixel strip,
// a LOGIC-LEVEL CONVERTER on the data line is STRONGLY RECOMMENDED.
// (Skipping these may work OK on your workbench but can fail in the field)
