Interfacing and configuring GSM module to Arduino

GSM/GPRS modules can be handy solution to wireless applications where wireless network isn’t available. JOJO have written pretty extensive tutorial on how to interface and configure common SIM900 GSM module with Arduino. GSM module interfaces to Arduino via serial interface with two wires for both direction of data flow. In order to reserve Arduino’s hardware USART for debugging and programming it is recommended to use different pins along with Software Serial Library. GSM module accepts AT commands so it is easy to program it, send SMS and even make call. Once you successfully send SMS with your desired data, you can start working on a project that sends data or alerts via GSM network. Continue reading

Feature rich scooter computer with touch screen

How about making a high tech scooter? It’s actually pretty easy to do with some extra cash. Well seems this project isn’t very cheap, but ads real value to regular scooter. So called Scooterputer has some hardware on it that is based on Arduino Duemilanove. First of all it has a touch screen – no need for buttons. Other things include: temperature sensor, DS1307 time and date RTC chip. Additionally there is an accelerometer and finally GPS and GSM chips. With this entire periphery computer is able to monitor battery voltage, track time and date, sense environment temperature, measure lean and gauge, track speed and trip distance. With GPS you get compass and position data. With GSM module Arduino is able to send SMS along with latitude/longitude data, heading, speed, and a time stamp data. Also GSM module acts as security system if unauthorized use of scooter is detected. Continue reading
