I will demonstrate how to create a 7 segment display using LEDs. Use Arduino in conjunction to make countdown timers, basic text displays, and additional features. I enjoy creating unique projects. I looked through all of instructables and couldn’t find anything similar to this. Actually, I looked on Google but found no results. This idea

edit: Wow, this won an awesome prize! Very many thanks guys! Charlieplexing (http://wealoneonearth.blogspot.nl/2013/03/design-note-charlieplexing-led-matrices.html) is a powerful method for driving a large number of LEDs from a relatively small amount of IO pin and without using any extra components. The technique makes use of the fact that a LED will only let current through in one
Concepts So you know what a switch is, but what can you do with it? One of the uses of a switch is to tell the controller to activate/deactivate different components. In this case we are going to use the switch to turn on and off an LED. We will do this by checking to

Laser Command is a game which I build using a 8×8 matrix LED and an Arduino Mini. This game was developed as a “sample” class project in S10-05833 Gadgets, Sensors and Activity Recognition in HCI. The class is taught by Scott Hudson at Carnegie Mellon University, and I’m doing TA for the class. The name

THERE MAY BE 9 STEPS BUT I PROMISE THIS ONE IS QUICK AND EASY! In this Instructable I will be showing you how to create a light reactive LED system. In this clip, I used a single color LED strip, but you you can use a single LED, multiple LEDs wired together, single color or

One day I was sitting behind my desk at work and I got that weird need to build something, after looking around for a bit I got my eye on an LED matrix and that sparked an idea in my head : “I WANNA MAKE A TAMAGOTCHI”. So for those of you that don’t know

Hello everyone, and welcome to my Instructable! This instructable will show you how I made the first ever DIY Arduino controlled “LED Kaleidoscope”! What is an LED kaleidoscope? Well, our traditional kaleidoscopes used 3 mirrors joined as a triangle with stuff like sequins and stolen cake decorations at one end, to create an awesome pattern

One of my clocks stopped working – and it happened to be a clock my wife likes a lot. Went to the repair shop and the guy said that he didn’t have the spare parts and could not repair this. So – I thought – why not build an LED clock – I had tons

This instructable will show you who to build a rgb lighting system with an Arduino. You can also control it with an iPod/iPhone/iPad using touchOSC. In my previous instructable I showed how to control one rgb led in this you can control heaps with a single chip the ULN2003A. Step 1: Parts You will need

You might remember my first set of lights that I put on my dad’s skates. Well those weren’t bright enough and they were a lot of work because I didn’t know how to make PCBs. In this i’ble I’ll cover how to make your own custom PCBs in under an hour! Keep in mind, if
