This project by Collin uses a familiar schematic — the light-sensitive oscillator (aka “phototheremin”) as originally described in Forrest Mims’ book Timer, Op Amp and Optoelectronic Circuits & Projects.
Many an experimenter, hacker, tinkerer, & maker have heeded the call of the mighty matrix – and it’s no mystery why.
Long before the dawn of digital music, folks employed the power of the electric color organ (aka “light organ”) to add some synced visuals to their hi-fi experience.
Using the Arduino development platform you will learn how to display numbers and letters on a single 7-segment LED display.
This is a modification of the LED jellies contributed by Angela Sheehan.
The colour USB fax printer was begging to be liberated from the dumpster.
When I first started working with microcontrollers, I had an Arduino, a few LEDs, a handful of DC motors, and very little common sense.
In this project, we will wire in a sensor and add a program that I made myself, so that our TVs greet us when we walk in the room.
If you are looking at this project, make sure you have seen my previous one, Getting Started with Arduino Clones.
Here you will learn how to wire the Arduino clone up and how to start your first project.
This project is a very straightforward guide for converting an old PC power supply box with a cooling fan into an AC powered, activated carbon fume extractor.
Take a picture is a fine-art project by artists Brad Blucher and Kyle Clements.
