Misc Projects : High Power RGB LED Controller

This is an ongoing project to control a number (currently 5) of Lamina Atlas high power (350-500mA) LEDs. Current progress includes: PCB artwork (in Eagle) with connections for 5 RGB LEDs. Firmware for a Microchip PIC16f887 microcontroller to interface between the FTDI 245R USB chip and a number of Texas Instruments TLC5940 constant current LED drivers. Python ctypes interface to libftdi. A simple Python in ...

Aurora 9×18 RGB LED art using PIC24F08KA101 microcontroller

Aurora 9x18 RGB LED art *** Check out my blog for updated version of this project and more! *** My obsession of LEDs has led me to this. Aurora 9x18 is a thing of beauty (if I can say so myself) - has 162 RGB-LEDs in a circular configuration. The color of each circle is controlled by a microcontroller using a twisted form of PWM. The microcontroller (PIC24F08KA101) only has one PWM module, yet Aurora is cap ...

Aurora mini 18 using PIC24FV16KA302 microcontroller

Aurora mini 18 My obsession of this year is full-color LED. I have made Aurora 9x18 as a result. As much as I love the scale of Aurora 9x18, I also wanted to have something smaller, perhaps something that can go on a costume? Here's Aurora mini 18. It has 18 full-color/RGB LEDs on a smallest possible circle. With a single PIC microcontroller, changing 18 RGB LEDs smoothly is reaching the technical limit. Wi ...

RGB LED Color Cycling Circuit

How to re purpose a the RGB LED color cycling circuitry from a Glade LightShow air freshener. I was in the process of creating a red, green , blue color cycling circuit based on a PIC microcontroller when I spotted the Glade LightShow air freshener. I wanted to know if it could be hacked up and used for other purposes. I found a couple of online coupons and when it went on sale in the store, I got 2 for $3 ...

Trippy RGB Color Mixing NightLight

Project is based on A Trippy Crystal Nightlight by Charles Platt in Make magazine volume 25, see URL below for additional details. A fun and simple project to get started with PICAXE microcontrollers. http://www. makezine.com/25/electronics In this version an inexpensive (> $2.50) AC USB charger provides a traditional plug-in-the-wall nightlight form factor.  I removed download circuitry from the main ci ...

RGB REMOTE (pinguino+web+linksys) using PIC18F2550 microcontroller

RGB REMOTE (pinguino+web+linksys) This project has several uses, it is basically a way to control an RGB LED group (tricolor with common ground) via a web page to select which color we want to show. It may be a way to harmonize a room, change the color of a swimming pool or just fooling aroun Step 1 RGB REMOTE webserver and serial connection In my case the web server is in Linksys router which I have "hacke ...

How to use an RGB LED – Arduino Tutorial

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. In this tutorial you will learn how to use an RGB LED with Arduino and create unique color combinations. So, let's get started! Step 1: What you will need For this tutoria ...
