hey james

i have 2 pings as well but am having problems, i have adapted some code and can get the data from 1 ping through arduino into the software i am using, but when i adapted it for two sensors i seemed to have some problems, such as even if i set different delay times for the low high low pulses for each sensor, when i compile the code both the pings flash at the same time and are very erratic for instance when i move my hand back and fourth the act light seems to go faster and slower and sometimes just go crazy and i get scarred for the life of my duino, do you know how to solve this problem? any help would be greatly appreciated.

cheers,

rich

There are links to the code required to build this in the post. You can find the info here – http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1211534244/3

Thanks Ribeiro. I specified distances for each range sensors. If the distance between the sensor and an object (in this case my finger) is between, say, 15 and 20 cm, this registers as a button press.

Hi,

Great job! I have just one question: how do you detect you have touched the “button”?

Thanks for sharing your project,
