Introduction: Smart Phone Controlled Christmas Tree With RGB LED Strip

Since Christmas is here, we decorated this Christmas tree with RGB LED Strip for our Christmas party, and made it an smart phone controlled tree. XD. It sure will present a "last-minute" magic for the Xmas show.
Christmas is coming but stuck figuring out ideas for Christmas decors? Still thinking about putting LEDs strip and EL wires together? Simply puting LEDs and make them blinking is a has-been.

With just a mobile device that has Bluetooth4.0 (BLE), you can easily controll every single LED in the lace, program the LEDs individually and react to beautiful rythms anytime. Whatsmore, the kit can be divided conveniently into separate parts, so you can make more use in your Arduino project wherever you want to.

Step 1: Materials

Or you can get all the things above as a kit.

The controller of this kit:Bluno.
Bluno is an Arduino board which integrates with a TI CC2540 BT 4.0 chip with the Arduino UNO development board. It allows wireless programming via BLE, supports Bluetooth HID, supports AT command to config the BLE, and you can upgrade BLE firmware easily. Bluno is also compatible with all Arduino Uno pins which means any project made with Uno can directly go wireless! It needs Android 4.3+ Devices with BLE or IOS 7.0+ Devices.

Step 2: Connect the Components

  1. Connect the microphone module with the audio analyzer.
  2. Make the Bluno and V7 Shield ready.
  3. Connection with the audio analyzer and microphone.
  4. Next connect the cables for power supply.
  5. You can connect the VCC for Bluno and GND for Bluno.

Step 3: Download the Code and Control the Light!

Play BLUno APP app now available in iTunes App Store : Play BLUno
You can also rewrite the code for your own use, have fun!

can you calculate how much it will cost in Euros because latvia now is using euro and more is that android phone ???? if i included mistakes in text please sorry me i am a latvian :D

Is the source code for the iOS 7 app available for download?

i did not understand how you can control each led in strip? is it a kind of special strips? all i seen in markets are parallely connected leds, it's unable to control one led. only one color of all leds.

The protocol is called NZR and the way it works is - the control string coming from the Arduino consists of a long series of 24-bit color codes, one for each light in the chain. The micro controlling the first LED on the chain uses the first 24-bits to set the color of it's LED and then strips it from the control sting, which it passes on to the next micro in the chain. So each micro in the chain uses the first 24 bits it gets and passes on the rest. Pretty clever.

Oh, I am not sure if the chip controlling the LED is a micro or just a custom special-purpose IC made to do this one thing - probably the latter.

As I known, this led strip integrates the IC inside it. So the LEDs is able to store the rgb color data sent from the controller, just like including a shift out register.

Yes, it is a kind of special strip and each led has a chip for the controlling. The chip in this strip called WS2812, you can download its datasheet from http://www.dfrobot.com/index.php?route=product/product&product_id=1077, so it is more expensive....But you can control every led not only turning on or off but also the color of each led.
