![]() I’ve noticed that others have started similar projects only to find out that they bought the wrong parts, or forgot to get parts that are needed. Planning is everything in this project, so before we begin: I highly recommend reading this article all the way before going shopping for LEDs etc. More details on the configuration later on, just keep in the back of your head that these 3 items (device name, baudrate and prefix) are critical for your Ambient TV lighting to work! Boblight Shopping list, or: What do we need? This prefix needs to be defined in the boblight config file, so it know to send this, and it needs to be defined in your Arduino Sketch so it can recognize it. ![]() This prefix can be seen as a “code” to identify the “beginning” of data for all LEDs. To make sure your Arduino knows when to start with the color of the first LED, a “ prefix” is being send. This speed must be identical for both devices otherwise they will not understand each other.Īs you can imagine, this process will happen in a blink of an eye video is displayed, analyzed, converted, send through the serial connection to the Arduino, where it’s then converted and sent to the LEDs which each have to be turned on as well. So in the example “/dev/ttyACM” or “/dev/ttyS”.īefore communication over this USB serial-port can be done, both XBMC and Arduino need to know what communcation speed ( baudrate) needs to be used. Look at the last column, and investigate/test the devices that end with “serial” in the last column. dev /vc / 0 /dev /vc / 0 4 0 system:vtmaster dev /console /dev /console 5 1 system:console dev /tty /dev /tty 5 0 system: /dev /tty OpenElecLivingRoom:~ # cat /proc/tty/drivers 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. 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. Some smart guy(s) created Boblight, which is opensource and can run (for example) on your XBMC computer. ![]() Until now though, and only for XBMC (Kobi) users. You will have to buy a Philips TV with this feature, … 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. 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. Back in the day, when the first LED TV’s appeared, Philips came with a great feature: Ambient TV lighting.Īmbient 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.
