This project is a solar powered Arduino based weather station and digital thermostat. Device is able to display temperature, humidity, barometric pressure and time/date. The sensor used is a SHT21 Temperature Humidity sensor. It is also equipped with a RGB led to display how comfortable the conditions are.

This project is a big LED matrix controlled by Arduino board and build inside an IKEA table.
The displays are connected to the Arduino to share the row select pins (A,B,C and D) and the control lines EN, CLK & LATCH. The serial lines R1,R2,G1,G2 have their dedicated pins. So there are 19 pins needed out of possible 20 (not counting the reset pins as I/O). As the displays are loaded in 16 rows a 64bit some transformation has to be done while loading the display.

Xoscillo is a software oscilloscope that acquires data using an Arduino or a parallax.
- Panoramic view
- Load and save waveforms
- Zoom in and out
- Can open several waveforms at the same time
- Can run several oscilloscopes simultaneously
- Frequency analysis using FFT
- Works on Windows and Linux (needs mono)
- Autodetects the hardware

This is an Arduino controlled light sensing switching unit. Its main use is to control solar lights to turn on when it is dark outside, but it can work in many more applications. This guide will walk you through every aspect of the building process. Prior knowledge of the Arduino unit is not necessary since the code and schematic have been supplied for you. This project would be fairly complex to build without an Arduino; it is a good example of how a microcontroller can make a circuit far less complex, with less hardware trial and error.

Arduino is well known among electronic hobbyists for it’s simplicity. Now it’s time for two new boards. Arduino has introduced two new boards Arduino Uno and Arduino Mega2560 introducing significant upgrades in Arduino concept. The biggest change is USB to serial converter as it doesn’t use FTDI chip FT232RL but Atmega8U2 that has hardware USB interface. Arduino also decided to change bootloader with new Optiboot firmware that brings some improvements as well. New Arduino boards are still compatible to all shields and also code can be ported from older versions. Check details on the links below.
The DrinkShield is an open source Breathalyzer kit for the Arduino. The DrinkShield can work as a standalone breathalyzer or you can connect it to a computer for and interact directly with the results. Source code repository comes with a game to use as a proof-of-concept.

Modkit is a graphical interface for programming Arduino and it works by drag and drop code blocks to make a complete program.
Modkit is a new kind of graphical programming environment that makes programming things in the physical world as easy as dragging and dropping little virtual code blocks in a web browser.. Heavily inspired by the Scratch programming environment (from MIT Media Lab’s Lifelong Kindergarten Group), Modkit enables anyone including kids, artists and inventors to build with electronic kits and components including motors, sensors, lights, sound and the popular Arduino and Arduino compatible development boards…
