RGB LED

Mixing red, green, and blue sources to produce white light needs electronic circuits to control the blending of the colors. Since LEDs have slightly different emission patterns, the color balance may change depending on the angle of view, even if the RGB sources are in a single package, so RGB diodes are seldom used to produce white lighting. Nonetheless, this method has many applications because of the flexibility of mixing different colors, and in principle, this mechanism also has higher quantum efficiency in producing white light.

LDR Color Sensor

“With the intention of building a cheap and simple color sensor to do projects with our students, we found an idea that seemed to allow us to do this with a simple LDR photoresistor and an RGB LED. Let’s …

OpenTama: an open source reference design for MCUGotchi !

“Last year, I introduced MCUGotchi, a Tamagotchi P1 emulator for microcontrollers, that worked on an STM32F0 development board. Today, I am pleased to announce the support of a new board in MCUGotchi: OpenTama ! OpenTama is an open source development board …

Illuminated Cubes

“This project is a follow up of the Illuminated Presents project that I posted earlier. My wife really liked the Illuminated Presents but kept them as Cubes and did not put a bow around it to turn them into presents …

DIY Rainbow Solar Mason Jar

“In this Instructable, I am going to show you how to make a Rainbow Solar Mason jar. This is a great project for people with minimal electronics skills, you can make this within an hour. This is an inexpensive and …

Another 5x5x5 RGB LED Cube

“This is the forth cube project I have posted here. I said in the third one that it would be the last, but this cube is a whole new way to build cubes - much easier, using LEDs very similar to …

Super-Sized RGB Seven-Segment Display Lamp

“I will be showing you how I constructed my Super-Sized Seven Segment Display RGB Lamp although you probably already gathered that from the title 😄. As seen in the images above, this project will be a scaled up version of a …

Touch Sensitive RGB Light Made From Paper

“Intro: As a former game designer, I know that kids love to play and interact with technology. Usually, creating interactivity needs programming or complex circuits. To get interactive fun easy, I created this simple and modular RGB Touchcube. It’s …

Arduino Chandelier From Jars

“I wanted to give my room some special design, with mooth lighting so when I had the option to use RGB leds and a Arduino board I decided I needed my own making a chandelier.”

RGB-LED Wire Tree

“I want to a share with you my RGB-LED wire tree. One evening I remembered building wire trees as a kid. Nowadays I really enjoy building small electronic projects with microcontrollers similar to arduino, especially with LEDs. So i …

The Pendant Lamp Clock

“Hi everyone. Imagine the moment when someone asks you the time and you tell the exact time looking at your pendant lamp!! Today I will show you how to make an amazing pendant lamp which tells you the time. It …
