Tronixstuff has published the first part of their tutorial series on using a GSM cellular modem with the Arduino. In this part they cover hardware interfacing and testing, sending a text message, and embedding data within a message. This part is the latest is a series of Arduino tutorials posted by Tronixstuff.

This project shows how to use the BMP085 Barometric Pressure Sensor with Arduino. The BMP085 pressure sensor combines a absolute barometric pressure sensor (aka barometer) with an temperature sensor and communicates with arduino using I2C protocol.

The Tweetagraph uses an Arduino to capture the dots and dashes created by the telegraph. The Ardruino itself is running Firmata (now comes as a built in library with the arduino software) so that it can talk to Processing. The Processing sketch is using the java library twitter4j which handles the communication with the Twitter API.

Building and coding the Arduino Lol Shield has been a lot of fun. My next goal will be to create a game of some kind. I know others have created Pong and Space Invaders. I’d like to come up with something different. Any ideas?

If you want your programs to run more faster or want to squeeze bigger programs to fit in to MCU here is a solution. [via]
Having been frustrated with many of the inefficiencies of the Arduino core libraries, we have built an alternate set with performance and size in mind. Alastair has given a talk at the Canberra Linux User Group about this library – the slides can be viewed on SlideShare.

This project is using the Adafruit protoshield to build a four-contestant gameshow system. RoysterBot writes:
If you have ever watched a TV quiz show you have probably seen contestants trying to press a button in order to win a chance to answer a question. The contestant’s quick reaction time results in some kind of light and/or sound indicating victory. This is a practical way to choose the next focus of the game’s activity and it adds a bit of excitement to the process. So when the holiday party planning committee decided to have a trivia contest I decided to build a quiz contestant lockout system to add an extra dimension of fun to the festivities. This would help the planning committee’s mission of creating some entertaining activities for the event.
The minimum requirements were to have a system with multiple buttons that contestants press for a chance to answer a question. The first one to press the button would lock out the other contestants. The system would need to have a simple way to quickly identify who pushed their button first. And finally the system would need to be reset for the next round.
Considering the venue of the holiday party (an upscale wine bar) I felt that the contestant buttons would be one of the most important features. They needed to be hefty and able to withstand abuse by hoards of “beverage enhanced” partygoers.
