John Boxall over at Tronixstuff has a series of Arduino tutorials. This chapter fifty-one of a series will show you how to use MC14489 LED display driver ICs with Arduino: Recently we’ve been looking at alternatives to the MAX7219 LED display … Read more
Here’s an Instructable by ASCAS: Phone macro photography (HQ – using LED lens) You can purchase some macro lenses for your phone camera but with a bit of work and a spare LED lens you can make your own. Only thing … Read more
In this video Nick Johnson demonstrates his tiny Minimatrix project and wrote a detailed explanation describing the build: While minimatrix is in principle a pretty simple device, there’s a surprising amount of detail that goes into getting it right – … Read more
Viktor added cool light effect to a translucent XBOX360 wireless controller: I didn’t want to use an arrangement where the lights would be on for an extended period of time, because that would lead to very short battery life in the controller. … Read more
MobileWill built this LED Matrix link project for his wedding: i just wanted to share my latest project for my wedding but i have also listed on tindie. I made a easy way to use the led matrix with the max7219. … Read more
Elpis shared his GSM/GPRS micro dev board in the project log forum: It is a 70×43.7mm control board (the PCB is made from SeeedStudio) designed as a part of a bigger project. But since the beginning I was trying to make it … Read more
Embedded Lab’s new version of MAX7219 based 4-digit serial seven segment LED display: This (SPI7SEGDISP4.40-1R) is a revised version of the previous SPI seven segment LED display (4 digit) board that displayed numerals and decimal points. The new version has … Read more
Rwinscot posted about his RickPAW RGB encoder w/ LED ring project. It’s a encoder breakout board, with a ring of LEDs designed to display the current position of the encoder. The LED’s and encoder are controlled via a microcontroller which … Read more
The light intensity of LED’s drops over time. Bogdan wanted to figure out exactly by how much the light intensity of his LED strips dropped, so he build a light intensity logger. It’s basically a closed box with an LED … Read more
Here’s an interesting art piece for your living room. It’s a Bluetooth controlled 32×32 LED matrix mounted in a picture frame. It’s designed to display pixel art uploaded from your android device. The LED matrix is controlled via an Android … Read more
Want a simple light show in your room? Here’s an Instructable on how to build your own. The Color organ is all analog and built from only transistors, resistors, capacitors, and of course LEDs: Audio source can be any “line … Read more
Sound controlled LED light show for your Xmas tree. An STM32 microcontroller takes instructions from a PC via Bluetooth and animates the LEDs. This is my Christmas tree, it has over 400 lights (exactly 404) that are all individually controlled … Read more
Here’s a fun project in the Christmas spirit. It’s a “Jingle bells” playing card, with the specific notes being signaled via LEDs as they are being played. We have 9 control lines for the LEDs and 1 line for the … Read more
Luca wrote a tutorial about LED matrices with HT1632C controller.
Like large things that light up? Here’s a Arduino based stage design consisting of eight large wooden letters lighted by 110 LED modules. Arduino and application code are released on GitHub. I made with some friends an Arduino based Stage … Read more
Order a single surface mount LED, you expect a small “anti-static” bag with a tiny LED inside. Wrong. Here’s what Systemstech got when he ordered one. A large “anti-static” bag, with a dehumidifier bag, and a humidity sticker inside. The … Read more
Add some LED goodness to this year’s Halloween pumpkins. This flickering LED design on a pumpkin shaped PCB was drawn up in KiCAD. Grab the design files from the low voltage labs site. It’s a simple schematic with just a … Read more
Community at it’s best, one forum member helping another. Matseng sent a Rino3 clock PCB to Arup, which he populated even before the Matseng got a chance to build his own. They are now debugging it together: Few days ago … Read more
Image by kaktuslampan: CC BY-SA Probably the most used device in out projects is the humble LED. They’re in almost every piece of equipment around us. While LEDs are simple to use, we get a surprising number of requests for … Read more
Hmms shared his Bluetooth controlled RGB LED strip project. Atmega8 microcontroller with the Arduino bootloader controls the LEDs, while the Bluetooth communication is handled via a cheap serial to Bluetooth module. I wanted the strip to be Controllable via a … Read more
