Daniel build this clock after having to chose from a watching a movie or working on a project. Obviously he and hi’s friend chose to make the clock so it wassn’t long until the LED’s started to light up. The clock code is based on the open-source-arduino-clock by Rob Faludi. Daniel made many changes, but the time counting the basically the same. So if you want to make another kind of clock, I suggest you to take a look on that code.

These days more and more temperature sensor projects appear on the internet so the world must be in need of temperature sensors 
. Daniel got hi’s done and up on the blog. The project is based on the LM35 Precision Temperature Sensor and the Arduino. He also plans on building a temperature sensor with max/min + clock and LCD, he promisses to post it on the blog when its finished.

Keith published a new article regarding a rotary encoder, the little potentioemeters that can spin forever. The article is about a Led calculator that he planed building for a while, and since the circuit has a rotary encoder he gives you some info about rotary encoders.

The first step on the project is joystick control of a servo over a USB connection. The end result which will make the project complete would be a RC rover monitored and controlled with a laptop and joystick on a WiFi network. The first step is already finished and the author managed to control a servo with the joystick.

The schematic shows that wiring the LCD to the HEF4094 is a simple operation. It has been drawn in a way that makes possible to develop this as part of a single sided PCB including a variable resistor to control the LCDs contrast. Note that the pinout of the LCD module may differ slightly from the pinout depicted; some LCD modules have pins 15 and 16 on the left side, before pin 1.
