/****************************************************************************
* 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
