This year i want to decorate my house for Christmas.

I have arduino and led strip ws2811 ; what's all good !

It's need a good idea to be original ; it's with twitter !!

I heard about the cheerlights project; it's a good idea.

I'll make the Tweetmas tree !!

Step 1: The Skeleton

The first step is to make some (scratch) sketch !!

I choosen wood because it's easy and you can make mistake

I taken square wood section 25/25

The top angle is 90 ° and the over angle are 45 °

I put some pipe supports for the strip

Step 2: The Strip

It's neopixel strip with ws2811

I buy them on ebay , there is a very good seller it's jianzhou1984

He is very honest and he have very quick shipping from china to France.

I taken 3 meters and put them in a white flexi pipe .

Step 3: Cheerlights

Did you heard about Cheelights projects ?

First go to Cheerlights page

All is explained on the cherlights.com, you can change the collor of the world by tweeting a color .

To see the curent color : what's color is ?

To control the world !

How to control CheerLights
To control CheerLights, send a tweet to @cheerlights or include “cheerlights” somewhere in your message with the name of a color.
Example Tweet: @CheerLights Paint the town red
This will cause a chain reaction and all of the CheerLights controllers will change their color to red, since “red” is a supported keyword.
CheerLight Colors and Commands:
red
green
blue
cyan
white
warmwhite
purple
magenta
yellow
orange
pink (Added December 2013)
oldlace (Added January 2014 - same color as warmwhite, but it is now a standard HTML color name)


Step 4: Arduino

How to control Arduino ?

Cheerlights work with Thingspeak , there is a channel(1417) on Thingspeak.

You didn't need a Thingspeak account to send request to the sever !

You need :

BOM:

1 Arduino board

1 Ethernet shield Like this one

1 set of screw shield like this one

1 power supply 3A 5v

1 ethernet cable

One over favorite seller on Ebay is gc-supermarket

Step 5: The Code

Coding for me is a pain !!!

I shearched on the web working arduino sketch.

Lot's of them don't work but i find this guy on youtube:

Leroy Miller

He does a good job and give a good working code on his codebender :

codebender

I cooked his code with more patterns like : candy cane , Theatre style or rainbow wheel

This is my working code:

#include <SPI.h>
#include <Ethernet.h> #include <Adafruit_NeoPixel.h> // Local Network Settings byte mac[] = { 0xBC, 0x2D, 0x41, 0x70, 0x07, 0x98 }; // Must be unique on local network #define Brightness 5 //Set brightness to 5/10th // You can adjust brightness #define Full (255/Brightness) #define thingSpeakInterval 18000 // Time interval in milliseconds to get data from ThingSpeak (number of seconds * 1000 = interval) // Variable Setup long lastConnectionTime = 0; String lastCommandString = "black"; boolean lastConnected = false; int failedCounter = 0; Adafruit_NeoPixel strip = Adafruit_NeoPixel(167, 6, NEO_GRB + NEO_KHZ800); // For me 167 pixel on my strip // Initialize Arduino Ethernet Client EthernetClient client;

Serial.print("CheerLight Command Received: "); Serial.println(lastCommandString); delay(200); } // Disconnect from ThingSpeak if (!client.connected() && lastConnected) { Serial.println("...disconnected"); client.stop(); } // Subscribe to ThingSpeak Channel and Field if(!client.connected() && (millis() - lastConnectionTime > thingSpeakInterval)) {subscribeToThingSpeak(); } checkcolor(lastCommandString);

Step 6: Videos

soon over videos!!

<p>totof60 - I got a new Cheerlight project for this year - I did change the code slightly, it's pretty much the same, but thought you might be interested in seeing my lightsaber cheerlight.</p><p>https://youtu.be/Ox1UNJYxRN0</p>
<p>I have converted the code such that it works with the small esp8266 ESP-01 board with the Neopixels connected to GPIO2 through a 3.3v - 5V level shifter. The code can be found on Github here: </p><p><a href="https://github.com/pepperm/esp-cheer-lights/blob/d5d4b890891f8003ec45813a63a62a025f353b13/esp-cheer-lights/christmaspatterns" rel="nofollow">https://github.com/pepperm/esp-cheer-lights/blob/d...</a></p><p>The image is of my dev board with just 6 Neopixels attached.</p>
<p>Very Nice, was just thinking I need to replace the ethernet shield with a ESP device, so I am glad I checked in on this project again and saw someone saved me some work.</p><p>Thanks! :-)</p>
<p>good job </p><p>thanks for sharing the code </p>
<p>Here are some pictures of my finished PCB. I use a 74HC126 to level shift from the 3v3 ESP-01 output to the Neopixel 5v. I do get some artifacts but if anything that adds to the spectacle. I have the Eagle files if anyone is interested.</p>
<p>good news and good job </p><p>thanks for your update</p>
<p>The Candy Cane effect is very neat! and get activated when RED is the Cheerlights color.</p>
<p>Yes i mod the patterns :</p><p> red is candy cane ( red and white)</p><p>Green is alternate green and orange</p><p>White is rainbow </p>
<p>Is the code shown missing the CandyCane routine though? The INO download has no line endings so I cut and pasted the text and don't have any CandyCane Void.</p>
<p>Great display ..</p>
<p>Very neat project, better then mine :-) I like your patterns too.</p><p>So, it's time to put them to work for me LOL</p><p>Marry Tweetmas! </p>
<p>big thanks for your comment</p><p>this project never born without your code. thanks for your help.</p>
<p>if you like you can vote for me in the contest !!</p>
