The technology behind Enigma machines and the work done to crack them has influenced cryptography, cryptanalysis, and computer science in general. If you’re unfamiliar with Enigma machines, it’s a device that was developed near the end of World War I, then used extensively by the Nazi regime in World War II, to encrypt messages. The […]
Video not playing? See it on YouTube: http://www.youtube.com/watch?v=q0tiiWwC6Zo Background Every Christmas we set up a large LEGO train layout in a section of the living room. This year, I ended up winning an eBay auction for a number of older-model LEGO road plates, one of which included a T-intersection. At about the same time, I […]
For a party we were about to have I wanted a cool light display to use with my new Xmas present – an Arduino Uno. Having looked at the LED matrix’s here I wanted a bigger one that I could hang on the balcony. I also wanted it to interact with music and flash at different sound […]
In this instructable I will show you how to make a 4x4x4 LED cube that will be controlled by an Arduino Demulionove. now yes you might say” that Arduino has only 14 I/O pins well also the 6 analog pins can be used as pins 15,16,17,18,19,20. that way giving us enough pins (16 columns + […]
Arduino: Nokia LCD & Sensors PROBLEM: Making my Arduino, a Temperature-Relative Humidity sensor and a Nokia3310LCD screen work together. Now, I’m a Lazy Old Geek, so what I wanted was an Arduino kit that would take shields. This Freeduino was the cheapest that I could find at the time. http://www.seeedstudio.com/depot/freeduino-usb-complete-kit-p-58.html?cPath=79_82 Since I was at Seeedstudio, […]
A couple of weeks ago, I published a great little controller module that provided 6 relays able to be controlled from a computer via a network. After I published it, I got to thinking that the same basic design, with a couple of changes could be pressed into service as a garden watering system controller. […]
This Instructable explains how to use a gas sensor with your Arduino. This lets your Arduino smell (and hence you program responses to) overall gas levels for a variety of nasties, including ethanol, methane, formaldehyde, and a bunch of other volatile organic compounds. My cost to make this actual device was under $100, including the […]
Yes, I know this has been done before, but I wanted to build my own, using as few parts as possible. I built this as a table top or wall mount model, but it can be scaled up to make a coffee table. I built it as a study for a more ambitious project, which […]
Create your own Super Bright LED-lined sneakers that blink with multiple patterns. 1.0 FEATURES: – 1 color LEDs – 6 patterns – reed sensors + magnets that give you control to step through patterns – detachable velcro design – small, wearable microcontroller + power Step 1: Parts & Tools Parts: Super Bright LEDs (35 or […]
THIS ENTIRE TUTORIAL IS ALSO AVAILABLE ON MY WEBSITE AT http://www.theparsley.com/arduino/diy/ To quote the Arduino website: “Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.” I got one a while ago and life has never […]
