This is a fun project that will surely impress anyone you make this for. If you are having a "Disco" themed party, you cannot have a boring old cake. Let me tell you, this is probably the only Arduino project that my wife has ever been willing to be a part of. She did the hard work of putting the cake together, and I, well.... I was in charge of lighting. My biggest fear was that one of the wires would come loose and ruin the event at the most critical moment... While a wire did come loose, I managed to fix it in time before the guests arrived. Ok enough of my monologue, let me show you how to make one of these things.
Note: powering this project using batteries is possible, but not recommended, and done at your own risk.
You will also need a Disco Ball Cake which you will have to make(or buy).My wife made this one. And as you will see shortly, the cake on the inside was Pink, because it was a strawberry cake.
You can get the Arduino IDE from here: https://www.arduino.cc/en/Main/Software
I used version 1.6.4, which is probably way out of date... but works fine nonetheless.
You can get information about how to use the FastLED library here: http://fastled.io/
And you can download it from here: FastLED Library
I used version 3.0.3, which is also probably out of date.

In this tutorial I showed you how to go about decorating a Disco Ball cake and also showed you how to use the RGB LED rings from ICStation. If you look at the video you will see just how versatile these LED rings are. I would like to thank my wife for providing such an exciting project to work on, and ICStation for their collaborative efforts. Please make sure to share this project with all of your friends and family.

Hi, I code a program for my autonomous robot. I am sending numbers from 0 to 8 from Raspberry pi to Arduino through Serial communication. I have Rasp code. But arduino code has some problems. Please can you tell me how to write it best? I want to use switch statement to choose direction for my robot/motors. But when I compile that code to arduino on robot - my robot start doing only default commands. Please why????
This concept to make a humanoid head, that speaks like a human, chooses phrases randomly. As (it) speaks , it moves head, eyeballs and eyebrows randomly in an emulation of a human. This can be useful for lonely people who cannot have a pet at home.
This is the basic idea..Later it is possible to develope it further to talk longer durations, and even tell short stories stored on an SD card.

Before you start any LED strip project, the first thing you will need to think about is POWER. According to the Adafruit website, each individual NeoPixel LED can draw up to 60 milliamps at maximum brightness - white. Therefore the amount of current required for the entire strip will be way more than your Arduino can handle. If you try to power this LED strip directly from your Arduino, you run the risk of damaging not only your Arduino, but your USB port as well. The Arduino will be used to control the LED strip, but the LED strip will need to be powered by a separate power supply. The power supply you choose to use is important. It must provide the correct voltage, and must able to supply sufficient current.

The NeoPixel strip is rolled up when you first get it. You will notice that there are wires on both sides of the strip. This allows you to chain LED strips together to make longer strips. The more LEDs you have, the more current you will need. Connect your Arduino and power supply to the left side of the strip, with the arrows pointing to the right. (i.e. the side with the "female" jst connector).
However, if you do not have a google profile...
