This project was originally written for an ESP8600 and re-written for a MKR1000 as it had all the necessities for the project without having to etch or solder a board for it (which was the original plan for the ESP8266-12E I had spare). The MKR1000 seems to be able to serve the page and run the functions a lot quicker too.
As the project uses the same libraries as the Arduino Zero and the MKR1000 is very similar, it should work on both the MKR1000 and the Arduino Zero (once the Wifi101 shield is installed).
For the video and picture examples I set the board up on a solderless breadboard to show how easy it is to implement.
Once the code is uploaded and the circuit is set up as directed go to the address (either specified in the sketch or 192.168.1.1 in AP mode) in a browser and click the button to send the instruction for each function.
Example interface
I'm hoping to include a colour wheel to choose the particular colour displayed in some functions at a later date.
Directions:A. Hardware:
1. Connect VCC to the V+ line
2. Connect Gnd to the Gnd line
3. Connect a 1000uF electrolitic cap between V+ and Gnd
4. Connect a 470 ohm resistor between the data pin on the neopixels and pin 12 on the MKR1000
5. Connect the Neopixel 5v and Gnd lines to the V+ and Gnd lines of the breadboard
6. (Optional) Connect a Lipo Battery to the charger (700mAh minimum)
B. Software
1. Download and Unzip the files or copy the code from the Code section
2. Open the Arduino IDE
3. Install the MKR1000/Arduino Zero board from the boards manager
4. Install the Wifi101 library from the Library manager
5. Run WiFi101_AP_Neopixels.ino in the Arduino IDE or paste in the code
6. Assemble the parts according to the description
7. Make any modifications you deem necessary (Wifi name etc.)
8. Upload
9. Connect to the WebAddress
10. Issue Command
Image of Circuit
As Fritzing doesnt have the MKR1000 or Arduino Zero available I took a picture
1. Connect 5v to the 5v line
2. Connect Gnd to the Gnd line
3. Connect a 1000uF electrolitic cap between 5v and Gnd
4. Connect a 470 ohm resistor between the data pin on the neopixels and pin 12 on the MKR1000
5. Connect a Lipo Battery to the charger (700mAh minimum)
1. Connect 5v to the 5v line

WiFi101_AP_Neopixels - built for the MKR1000 but should work for Zero too
