##Test the LED strips

1. Install the drivers (The neopixel LED driver software is preinstalled on the colorberries.)

    sudo apt-get update
    sudo apt-get install build-essential python-dev git scons swig
    git clone https://github.com/jgarff/rpi_ws281x.git
    cd rpi_ws281x
    scons
    cd python
    sudo python setup.py install
   

2. Connect the LED strip to the custom hardware

3. Run the strand test

    cd examples
    sudo python strandtest.py
   

##Control the LED strips from the app We will write python script using paho-mqtt installed earlier and the neopixel library.
