Introduction The Lumenati line of LED boards is designed to give your projects an edge in their lighting capacity. Based on the APA102C addressable LED, these LEDs employ a 2-wire communication protocol consisting of a clock line and a data line. While this requires one more wire than standard WS2812B addressable LEDs, the advantage is that the communication […]

Introduction Besides looking damned good on an otherwise bland and ordinary desk, this project is about more than just being attention grabbing eye candy. It’s about demonstrating a small portion of our single board computer capabilities by hooking up a color sensor, RGB light strip, and enclosing it in a nice looking wooden enclosure. We’re

Story At thethings.iO we want to show you different ways of using our platform for your projects and products! For this reason, we have developed a prototype using a Raspberry Pi and our REST API to monitor the access to a room. The device, that should be embedded next to the door as you will

Project This project employs computer vision to ensure that your cat will have exclusive entry access to your home. The door is motion-activated, and will unlock only when it detects a cat face. As an exercise, you can extend this project by implementing any of the following features: A user interface to view photos of

Tibbo created two small programs that illustrate how easy it is to write MQTT-enabled apps in Tibbo BASIC or Tibbo C. To illustrate the use of the MQTT library, we have created two simple Tibbo BASIC applications called “mqtt_publisher” and “mqtt_subscriber”. In our MQTT demo, the publisher device is monitoring three buttons (Tibbits #38). This

RGB LEDs consist of a red, a green and a blue LED conveniently encapsulated in one package. Theoretically one such should be able to produce any colour of the rainbow, but I have restricted my project – for reasons explained later – to just red, green, blue, cyan magenta, yellow and white. The project uses

So I’ve been looking into this a little more. I took your guys idea of using the TLC5940 LED Driver. So now I’m asking for some help again. I figured 1 long question that eventually solves this is better then a bunch scattered throughout stackexchange. Now comes the wiring part. I’m using an arduino wiring
So we now have a traffic light/pelican (Tux!) crossing simulator. The 2nd Red LED is connected to wiringPi pin 3, (GPIO-22), and the 2nd Green LED is connected to wiringPi pin 4, (GPIO-23). Test them as before with the gpio command, e.g. for i in 0 1 2 3 4 ; do gpio mode $i

Overview of Steps In the first phase, I will install only one LED. Next, I download the LED class python module that represent one hardware LED. I will run the LED class python module to blink that LED. The first phase serves as a “Proof of Concept”. In the second phase, I will install another
In this brief guide we will show you how to connect up two LEDs to the GPIO ports on your Raspberry Pi and control them via Python Script.  From this point onwards I will assume that your Raspberry Pi has a fully working install of Raspbian and is connected to your WiFi or Wired Network.  Rather
