Modified code for SRF02 now it works properly
I return from the previous post on the SRF02 sensor, as I had previously written the following sample code on the site found a strange behavior on the measurement, asking friends who had the same sensor, but tested with software written in different languages had more behavior correct.
I then performed some tests with mbed, to see if changing the device sensor work properly, and in fact the results were positive, confirming that the sensor was faulty.

Managing an ultrasonic sensor SRF02
Finally it is time to get my hands on one of the ultrasonic sensors, which I keep in the drawers of the components, in particular I’m talking about the SRF02 sensor, an ultrasonic rangefinder that can make measurements between 16cm and 6m.
This sensor can be controlled through a serial or I2C, the choice of mode of control is administered through a 5-pin, which is connected to ground if you want to use the serial port, or left unconnected if you want to use the control via I2C. In this article I will speak of my experience with sensor controlled by a PIC 18F2620 I2C, and as you can see the management of the sensor is identical to that of a common I2C EEPROM. The details of the sensor and use them can be found at this link.
We begin to analyze the circuit diagram that is vary simple.

Romecup 2011
From March 14 to 16 there will be the usual manifestation of RomeCup three days dedicated to Robotics, the first two days will be held at the ITIS Galileo Galilei in Rome, while the final day will be held in the hall of the Capitol Protomoteca.
This is an event dedicated to the schools, but there are also other initiatives in Robotic, also some mention of the many presentations on Arduino, held by a friend of Roboteck, the group also cited in the event program.
Among the events scheduled are:
- Explorer Junior
- Explorer Senior
- Robocup junior open league
- Robocup junior light weight league
- Robocup junior Dance primary
- Robocup junior Dance secondary
- Robocup junior Rescue primary
- Robocup junior Rescue secondary
If you are interested, you can go for more details on the official website of the event the link is as follows: http://www.romecup.org/
