Sonar help, again

Posted by David spencer on December 6, 2011 at 10:20am

i've been having on-going issues with my sonar and wonder whether anyone can help?

i've used the terminal sonar test and with the sonar connected i get a continuous 20cm reading, no matter what and without it connected i'm getting 700cm.

i was concerned that the sonar was faulty so bought another which arrived today. just tested that and i'm getting exactly the same readings.

just updated to latest version of the code and been through the config - enabling the sonar etc

tested the votage from the oilpan connection to the sonar it's reading nothing - i was expecting to see 5v - pins are soldered correctly.

any ideas?

    Actually same problem here. Uploaded some recent code and always get that 20cm reading. Was also suspecting a faulty sonar as I haven't used the quad over the rainy season. I better double check then whats going on.
