This was a 2 hour project I whipped up in order to learn how to use a new Bluetooth LE 4.0 module I picked up at redbearlab.com, called a BLE Mini. I’ve since thought of several much simpler ways (and more dependable) to accomplish the same thing, such as simply lighting 3 LEDs behind weather […]
Build your own electric guitar tuner using the Arduino! I decided to make this because I wanted to experiment with audio input and frequency detection. I used Amanda Ghassaei’s method for Arduino Frequency Detection in order to get frequency readings using the Arduino. I used LEDs that light up according to the frequency of the audio input, […]
Ready-made SD card logging shields for the Arduino typically cost in the range of $15 – $25. This is quite reasonable, but we might save a couple of bucks if we make our own. Not to mention all the fun in building it. Forget about soldering wires to a bare SD card socket. It’s just […]
Protect your secret hideout from intruders with a lock that will only open when it hears the secret knock. This started out as a bit of a joke project, but turned out to be surprisingly accurate at judging knocks. If the precision is turned all the way up it can even detect people apart, even […]
I started recently to get interested in building Arduino based robots. Since it is a traumatizing process to take any creation apart, I am opting to keep mine alive and kicking. To lower the cost of this strategy it seems obvious to switch from the arduino development board to selfbuilt arduinos – DIYduinos if you […]
We all need to dream more so I’ve created this Arduino Powered “dream generator” to help plant the seeds for some big thinking craziness. When you approach the generator a Maxbotix ultrasonic sensor triggers lights and music that draw you in so you can stare into the blue LED enshrouded infiniteness of the box. Press […]
first of all we would like to thank the organisation and especially the main sponsor, Capgemini, which made all of this possible. This project is a contribution to the first belgian Arduino Jam (2012). During the Arduino Jam 2012, me and two other colleagues put our heads together to build an interactive logo. The idea was to use […]
I made this box for my music project to our school. This is only tutorial for the box, no for playing melody. It´s based on serial connected switches. You will need: Some wire 6x switch 1x LED 1x 330 ohm resistor 5x 2000 ohm resistor (etc.) 1x 10 000 ohm resistor 1x plastic box small […]
Time for another instalment in my irregular series of irregular clock projects. In contrast with the minimalism of Clock Two, in this article we describe how to build a different type of clock – using the “lilypad” style of Arduino-compatible board and components designed for use in e-textiles and wearable electronics. As the LilyPad system is new territory […]
Last month, Elecrow have left from the original office and moved to a new office. We will miss our original office where we worked so hard for more than two years, we will miss everything here, the desks, the windows, and those potted plants, that we cared for more than two years with our neighbor. […]
