Problem with Ultrasound Sensor

Gonzik's picture

Hello LMR.

I am working on a current project but seem to be having a ridiculous amount of difficulty implementing an SRF02 Ultrasound sensor. I am using it in serial mode and communicating with an Arduino Duemilanove. The problem is not in the wiring as I triple checked that.

The adruino is supposed to send 2 bytes to the SRF02 [ address, command ] and then receive 2 bytes in response giving the distance measured by the sensor.

Cheap Sonar

One of the most important parts of a robot is it's sensors. If it cannot sense it's surroundings then it cannot respond. Unfortunately good sensors are usually expensive. For this reason I am always experimenting with cheaper home made alternatives such as my light up antenna, conductive foam touch sensor, IR obstacle detector and my not so successful laser range finder.
