If you only care about showing content as clearly as possible at the lowest cost, then you’ll want to turn to LCD or OLED technology. But a project’s display gives you an opportunity to get creative with the aesthetic, which opens up a whole world of different display types. If you want a retro feel, […]
The childhood classic tabletop game of Connect Four entails dropping either a red or yellow disc into one of several columns in a grid with the hope of lining up four in a row. And even though the game has existed digitally for a while now, it is mostly played on LCD screens with fancier […]
If you’d like to integrate touch functionality to your LED project, then tuenhidiy may have just the thing for you. The setup uses 16 pairs of IR emitter and receivers arranged down the length of a bi-color 16×32 matrix to tell when one has inserted a finger or other object into an area. When sensed, […]
Consider that a digital camera uses an array of sensors to capture light from an object. Maker Marcio T, however, decided to turn this idea on its head and instead utilize an array of lights that are detected by a single sensor. The way it works is that as each LED in a 32×32 matrix […]
Glue sticks are great for attaching electronics and other bits to projects, but as Jon Bumstead shows in his latest work, they can also make pretty cool light diffusers. His project takes the form of a wooden box with plexiglass panels, allowing observers to see 64 vertical illuminated glue sticks inside. Hidden within the cube […]
Martin Atkins built this great LED matrix clock using an Arduino Micro, a few bicolor LED matrix displays, display drivers, and a real time clock module Chronodot: Finally found some time today to solder the parts onto my first OSH Park PCB. The primary motivation for this was to learn Eagle and try out OSH Park, so I wanted to make […]
I just finished a quick sample project for the Arduino Mega, doing a project that comes up all the time, and usually requires a multiplexer, Max7219, or shift register: controlling 128 LEDs with a Mega. In this example, there’s nothing but a mega and 2 8×8 LED matrices. Whee! And yes, that’s a nifty light […]
