Arduino – All LEDStrip effects in one (NeoPixel and FastLED)

Arduino – All LEDStrip effects in one (NeoPixel and FastLED)

If you’ve read the article I wrote a while ago “LEDStrip effects for NeoPixel and FastLED“, then you might have noticed quite a few requests to combine all these effects in one single sketch.

I have seen some users come up with some nice examples, but the challenge remained (for me): how do I instantly toggle from effect to another?

Well, today I’ll have such a sketch available for you; it allows you toggle between effects with a simple switch.

For those who have read the article “Arduino – Controlling a WS2812 LED strand with NeoPixel or FastLED” might have gotten infected by urge to get more effects, after all … some of these LEDStrip effects look pretty slick!

With the holiday coming up real soon, I figured this would be a great opportunity to create and post some cool effects for your LED strips. Maybe you can be your own Griswold (National Lampoon’s Christmas Vacation) with these! 

You’ve got to check out the Fire effect with toilet paper – looks pretty cool!

Please read the article Arduino – Controlling a WS2812 LED first, as it will show you some of the basics.
Also note that you’re invited to post your own effects or ideas in the comment section or in the Arduino/WS2811/WS2812 – Share you lighting effects and patterns here … forum topic.

The main reason why I bought my first Arduino board was to be able to play with LED strips with applications like BobLight and LightPack that offer colored backlighting to your TV comparable to what Philips offers with it’s beautiful AmbiLight TV’s.

I like really Philips, and I like Ambilight, so why not buy a Philips AmbiLight TV?
Well, pretty simple … first of all Philips does not carry 80″ AmbiLight enabled TV’s, smaller models are significantly more expensive than non-AmbiLight models, and it appears that these AmbiLight TV’s are hard to find in the US.

In this article we will be using an Arduino Uno connected to a strip of WS2812/WS2811 LEDs.

Getting started with the ESP8266 as an Arduino replacement

In this article, I’ll show you how I did get started with an ESP8266, as a replacement for an Arduino, and they are dirt cheap!

The ESP8266, appears to have been sold as a shield for an Arduino, to provide WiFi functionality to an Arduino. Pretty cool!
But what is even cooler: For most applications you do not even need an Arduino, as the ESP8266 can run as a standalone microcontroller with WiFi on board, and is even more capable than most Arduinos.

This may sound odd, but after my first experiences with the ESP8266;
I’m beginning to wonder how often I’ll be using my Arduino Uno in the future. The little ESP8266 is so cool, faster, more powerful, and has more memory, at a ridiculous price of about $5. And all this in a smaller package with WiFi included!

Ambient TV lighting with XBMC Boblight, OpenElec and WS2811/WS2812 LEDs

Back in the day, when the first LED TV’s appeared, Philips came with a great feature: Ambient TV lighting.

Ambient TV lighting consisted out of lights that would project to the wall behind your TV, one or more colors matching the content on your TV. So if the majority of the screen would be red, then the light emitted would be red, if the majority of the screen is green, then green light would be emitted, etc.

Over the years this has been refined to multiple colors, matching small parts of the screen. Unfortunately though, this wonderful feature is not something you can simply add to your TV. You will have to buy a Philips TV with this feature, …

Until now though, and only for XBMC (Kobi) users. Some smart guy(s) created Boblight, which is opensource and can run (for example) on your XBMC computer. The computer analyzes the video content and “converts” it to signals for LED strands, so you can attach these strands behind your TV and have a DYI Ambient TV lighting effect.

Note : This will only work for content played through your XBMC Media player (I used OpenElec)! So your regular TV shows, your XBox or PlayStation, none of these will have an influence on the “Ambient TV lighting” we will be discussing in this article.

WordPress – Increase Maximum Upload Size for Media Library File

My latest issue with WordPress has been the limited maximum Media Library Upload Size when I tried uploading a few videos for an Arduino article.

In this article I’ll show you several methods to increase the Maximum Upload Size for the WordPress Media Library, either by modifying php.ini, functions.php or the .htaccess file. WordPress MU/Multisite/MS use will be addressed as well.
