There’s a small reset button on the top. I found the casing itself in the wonderful store Material (http://www.materialbutiken.se) in Stockholm for just 15 SEK. It fits […] Read more

Currently it just prints the distance on the serial port, but will form the basis of a simple proximity alarm. I can recommend this SRF02 framework: http://www.grapelabs.org/arduino/libraries/srf02-ultrasonic-distance-sensor Read more
