The Arduino receives a message over serial and coverts it to morse code output on an LED connected to digital pin 13. The Arduino also simulates decoding the message back to plaintext using the LCD display. Programmed in C++.
WitchDoc was giving his Arduino Workshop at Hackerspace Hack42, covering the basics and working from there. It was great fun and educational.

Arduino DCF77 Signal Analyzer Clock. Uses dual Atemega 328 microprocessors to display the DCF77 signal, signal info, time & date. Displays are 3 Dot matrix LED and 4x LED 7 segment all controlled by 7 x Max7219 ICs.
Here we have created Arduino Interface with MySQL for storing RFID access details. This Sketch uses ARDUINO UNO, ETHERNET SHIELD, RFID MFRC522 & MYSQL. You can get its source code at github.com/DeligenceTechnologies/Arduino-interface-with-MySQL-for-storing-RFID-access-details and you can contact us at info [@] deligence.com in case you have any query.

A thermistor (temperature sensor) is connected to the Arduino's ADC input. The Arduino samples the current temperature once per second, and outputs the temperature on the connected LCD screen. Programmed in C++.
This was photo was taken while the Arduino was in my refrigerator. After taking the picture, I realized I had incorrectly calibrated the thermistor, hence why it is reporting a warmer temperature than it should be while inside my refrigerator ;)
