RGB LED Strip Controller

NewImage-20

Thomas Gonnot has published a RGB LED Strip Controller based  on STM32F0 microcontroller. The controller is able to power NeoPixel and DotStar protocol RGB LEDs.

A simple controller for a RGB LED strip, with independent control of color and intensity.

The design is based on a simple STM32F0 microcontroller. It can handle NeoPixel and DotStar protocols, and the power supply can vary from 5V to 15V.

SK6812 – a new intelligent RGB LED

sk6812

Tim discuss about a new RGB LED that appeared on the market:

During the last months, a new WS2812 alternative appeared on the market: The SK6812. I finally managed to get my hands on some of them to take a closer look. In most aspects these devices are basically clones of the WS2812. What is interesting however, is that the manufacturer came up with a couple of new variations of the stock 5050 RGB LED.

PWM dimmer for RGB LED

20160128_Projekte_061-600x399

Lukas Fassler has designed and built a PWM dimmer for RGB LED:

In my last post I’ve described the design and construction of my LED dimmer project. This project here is similar but a bit more involved. It controls RGB LEDs so it can not only change the brightness but also the color of the light. Instead of a simple pot it used a pair of rotary encoders with push buttons. One controls the brightness, pushing its button turns the light on or off. The other changes the color, pushing its button toggles between color and white.

How to use a Serial Voice Recognition Module

F6N94WJIG7H9VM4.MEDIUM

by codebender_cc @ instructables.com:

In this tutorial you will learn how to use a voice recognition – serial – module with the Arduino uno board. This module can store up to 15 voice commands. Those are divided into 3 groups, with 5 commands in each group.

First we should train the module with voice instructions group by group. After that, we should import one group before it could recognize the 5 voice instructions within that group.If we need to implement instructions in other groups, we should import the group first. Only one group can be active per time.

In this tutorial we will use an RGB LED and we will try to change the color of it with voice commands.

An RGB LED has 4 pins, one for each color (Red, Green, Blue) and a common cathode. It has tree different color-emitting diodes that can be combined to create all sorts of color! Any color is possible depending on how bright each diode is.

DIY FPGA-based HDMI ambient lighting

2015-04-21 21.57.31

by  Scarab Hardware :

Ambient lighting is a technique that creates light effects around the television that correspond to the video content. It has been pioneered by Philips under the brand Ambilight. In this project we will create a basic FPGA-based ambient lighting system that reads the video signal over HDMI. This means we are not limited to computer output. We can use it together with DVD players, video game consoles, etc.

Hacking a LAMPAN IKEA lamp to add RGB light and BT

by Jesus Echavarria:

This project starts a few weeks ago. My six years old daughter usually sleeps with a light on in her bedroom. Talking with her, we decide to hack her LAMPAN Ikea lamp to make some improvements, including a manual RGB controller to set the light colour, a timeout to turn off the light after 30 minutes without changes and a bluetooth connection to control the lamp with a smartphone or tablet. So, if you continue reading the post, you’ll see what we develop!
