Hi, I am having trouble in using the ultrasound distance sensor with the arduino board. the model is HC_SRO4 and has a vcc- trigger- echo and gnd pins. i am trying to get distances out of it while most online tutorials that i am checking is putting the echo and trigger into digital pins of the arduino board but my problem is if so how do I write the patch in pduino to get the distance.) I am using the pduino test patch to do the interactions but can't figure out how to generate numbers through a digital input.
If you want approximately accurate data from the HC_SR04, you have to measure it on the Arduino, which means customizing the Pduino sketch. A library and a demo sketch for the HC_SR04 is a good starting point, like: http://freecode.com/projects/hc-sr04-ultrasonic-arduino-library.
Thanks Sujay
