ArduinoPixel

This project consists of two pieces. The first piece is an Arduino sketch that implements a Web Server and offers an API for controlling a NeoPixel LED Strip. The second piece is an Android app, ArduinoPixel, that connects to the Arduino Web Server and sends commands to control the color and the on/off state of the LED strip.

The Arduino sketch is also available at codebender. You can clone the project, update the controller and network parameters, and upload it straight to your Arduino Ethernet, or any other Arduino compatible board w/ an Ethernet Shield.

The Android application is available on Google Play. Install the app to your phone or tablet, configure the network parameters you set earlier in the Arduino sketch, and you are ready to go. You can watch a demo on YouTube.

API

The server accepts the following HTTP requests:

  • A GET request to /. It responds with a Hello from Arduino Server message.
  • A GET request to /strip/status/. It responds with ON or OFF for the on/off state of the strip.
  • A GET request to /strip/color/. It responds with a JSON representation of the strip's color, e.g. {"r":92,"g":34,"b":127}.
  • A PUT request to /strip/status/on. It turns the strip on.
  • A PUT request to /strip/status/off. It turns the strip off.
  • A PUT request to /strip/color/. It changes the strip's color. The data are delivered as a JSON object, e.g. {"r":48,"g":254,"b":176}.

Testing

The Android app was tested on a tablet with Android v4.1.1.

Attribution

The Android app makes use of Piotr Adamus' ColorPicker view.

Thank you Piotr... with your beautiful work, you gave me the motivation I needed to attempt this project.
