Arduino powered temperature sensing RGB LED nightlight using PICaxe

About a year ago I started on a project to make a temperature controlled nightlight. I was inspired by seeing these lovely LED lamps styled as mushrooms growing out of pieces of wood. Those mushrooms were made out of glass, which was somewhat beyond my skills. However I then saw some had used translucent sculpey to make mushroom nightlights on instructables. So with that discovery it seemed like it would be ...

The ‘One Chip Spinning RGB POV Display’ with conversion software using PIC18f4680

The 'One Chip Spinning RGB POV Display' with conversion software. If you have been on the look out for a project that combines, RGB LED's, a motor, a microcontroller and a ridiculous amount of hot melt glue, then you have certainly come to the right place. Allow me to introduce the 'One Chip' Spinning RGB POV Display This project allows you to create (with minimal components) a fantastic customizable displa ...

Using the ChipKIT Basic I/O Shield With Analog RGB Strip LEDs

A few months ago I wrote a blog post about the chipKIT Basic I/O Shield and used Analog RBG Strips to demonstrate the the open drain FETs. This post is to give details on how to wire up the strip LEDs to the I/O Shield. You should already know how to program MPIDE before using this Instructable. Step 1: Gather Materials Gather your materials: Strip of RGB LEDs (12V) usually, you can get them fairly cheaply ...

How to drive an rgb led using PIC16F877A

The RGB LED contains three LEDs encased in one shell: Red, Green and Blue (some contain an extra blue led - as blue LEDs generate less output intensity (candela) per mA). It looks like a single white led except that it has four leads - one for the common ground connection and one for each led. Basic operation The average current through each of the LEDs determines it's light output i.e. its contribution to ...

Aurora 48 – 48 RGB LED Sequencer using PIC24FV16KA304

Aurora 48 is a compact and thin profile full-color LED sequencer. It's built entirely with surface mount components, so the profile is nice and clean. Features Capable of individually controlling 48 Full color LEDs. Each LED can be faded in 7 bit per channel - 2,097,152 colors. Gamma corrected brightness curve for very smooth fades. Simple, one button control. 11 sequence pattern (as of firmware version 1.0 ...

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 ...
