1/****************************************************************************
2 * This example was developed by the Hackerspace San Salvador to demonstrate
3 * the simultaneous use of the NeoPixel library and the Bluetooth SoftDevice.
4 * To compile this example you'll need to add support for the NRF52 based
5 * following the instructions at:
6 * https://github.com/sandeepmistry/arduino-nRF5
7 * Or adding the following URL to the board manager URLs on Arduino preferences:
8 * https://sandeepmistry.github.io/arduino-nRF5/package_nRF5_boards_index.json
9 * Then you can install the BLEPeripheral library avaiable at:
10 * https://github.com/sandeepmistry/arduino-BLEPeripheral
11 * To test it, compile this example and use the UART module from the nRF
12 * Toolbox App for Android. Edit the interface and send the characters
13 * 'a' to 'i' to switch the animation.
14 * There is a no delay because this example does not block the threads execution
15 * so the change will be shown immediately and will not need to wait for the current
16 * animation to end.
17 * For more info write us at: info _at- teubi.co

26// Declare our NeoPixel strip object:
27Adafruit_NeoPixel strip(64, PIN, NEO_GRB + NEO_KHZ800);
28// Argument 1 = Number of pixels in NeoPixel strip
29// Argument 2 = Arduino pin number (most are valid)
30// Argument 3 = Pixel type flags, add together as needed:
31// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
32// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
33// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
34// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
35// NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products)
36
37// NEOPIXEL BEST PRACTICES for most reliable operation:
38// - Add 1000 uF CAPACITOR between NeoPixel strip's + and - connections.
39// - MINIMIZE WIRING LENGTH between microcontroller board and first pixel.
40// - NeoPixel strip's DATA-IN should pass through a 300-500 OHM RESISTOR.
41// - AVOID connecting NeoPixels on a LIVE CIRCUIT. If you must, ALWAYS
42// connect GROUND (-) first, then +, then data.
43// - When using a 3.3V microcontroller with a 5V-powered NeoPixel strip,
44// a LOGIC-LEVEL CONVERTER on the data line is STRONGLY RECOMMENDED.
