it’s as simple as a clojure data – map and vectors. A map with a char as the key and the vector of bits as the morse representation. ;; 0 represents short signal ;; 1 represents long signal ;; Intermational morse from http://en.wikipedia.org/wiki/Morse_code ( def letters-2-bits {\a [0 1] \b [1 0 0 0] \c [1 0 1 0] \d [1 0 0] \e [0] \f [0 0 1 0] \g [1 1 0] \h [0 0 0 0] \i [0 0] \j [0 1 1 1] \k [1 0 1] \l [0 1 0 0] \m [1 1] \n [1 0] \o [1 1 1] \p [0 1 1 0] \q [1 1 0 1] \r [0 1 0] \s [0 0 0] \t [1] \u [0 0 1] \v [0 0 0 1] \w [0 1 1] \x [1 0 0 1] \y [1 0 1 1] \z [1 1 0 0]}) source: https://github.com/ardumont/arduino-lab/blob/master/src/arduino_lab/morse.clj <p style="text-align:right;color:#A8A8A8"></p>

Crash course: Embedded programming with Arduino
December 20, 2011, 8:00 AM — Demand for embedded programming is growing like crazy, so anyone looking for some job security might consider becoming an ace embedded programmer. It helps to have some programming experience, but even raw beginners can get started inexpensively and learn on their own. One of the friendliest introductions to embedded coding is Arduino .
Arduino is an open embedded hardware and software platform designed for rapid creativity. It's both a great introduction to embedded programming and a fast track to building all kinds of cool devices like animatronics, robots, fabulous blinky things, animated clothing, games, your own little fabs... you can build what you imagine. Follow along as we learn both embedded programming and basic electronics. What Does Arduino Do? Arduino was invented by Massimo Banzi, a self-taught electronics guru who has been fascinated by electronics since childhood.

It’s been a hugely busy and exciting year for us all at Cool Components. We’ve dispatched more orders than ever before, and are proud to have offered a shed-load of exciting and ground-breaking new products for sale! 2012 has been brilliant, so thanks to all of our fantastic customers, and we hope to continue serving you just as well in 2013 We’re kicking off the year with some very cool new products – first up this lovely robotics wheel.Taking a stock Ikea table, this hacker added a set of 81 individually controlled RGB LEDs to the frame, creating a glowing livingroom centerpiece. Using the Arduino , he can individually address each LED to control the color change. Now if only it was a VU meter which bumped to the beat of your music…Perhaps that’s another project Above is a photo of the LED array beneath the table. Definitely a superb job of cable management to say the least. More info on the project can be found on the author’s flickr page .  Finally, below is a video of the table in action. Do not miss out:

T he speed of the sound in the dry air (20° C) is around 343 m/s. Send a short ultrasonic pulse at Frequency of 40Khz in the air, and try to listen to the echo. Of course you won’t hear anything (only a little click noise), but with an ultrasonic sensor the back pulse can be detected. If you know the time of the forth & back travel of the ultrasonic wave, you know the distance, divide the distance by two and you know the range from the ultrasonic sensor to the first obstacle in front of it.
