Sonar sensors

StormKing09

Is there any way to incorporate a sonar sensor into a PBASIC program for a BASIC Stamp. This is mainly for the BS2 models such as the BS2, BS2sx, BS2p, BS2px and so forth. please reply if you can help

Of course. If you go to the parallax page for the ping sensor you can find plenty of downloads giving you information on·how to do it. Here's the link.

Also, does anyone know what the circuit diagram symbol would be for the PING))) sonar sensor? If you do, please let me know. tnx

For complex devices like a PING))), there's usually not any specific symbol used on schematics. The general "black box" symbol used would be a rectangle of some sort with the name of the device included. There's no particular convention for the connections either, but, if there are only a few, they're usually placed on one side. Sometimes the power connections are placed on the "bottom" and the signal connections on one side. If you want to be creative, you could add arcs on one side to imply the sound wavefronts, but the PING))) is much more than just the ultrasonic transducers. There's a microcontroller and a driver / pre-amp.

Whaaaaat? Try speaking english dude. I don't gibrish.

also, I can't get the sample codes off of the internet. can someone type it into a thread post?

Generally, some respect for others is helpful. A better answer might be "I'm sorry, but could you simplify that for a beginner? Thank you." Basically, what Mike is saying is that you'll want to use a box with the name PING))) in it. He gives some general placement of pins on the schematic.

Here's some example ping code:

' {$STAMP BS2}
' {$PBASIC 2.5}

' Conversion constants for room temperature measurements.
CmConstant    CON   2260
InConstant    CON   890

cmDistance  VAR   Word
inDistance  VAR   Word
time        VAR   Word

DO
  PULSOUT 15, 5
  PULSIN 15, 1, time

  cmDistance = cmConstant ** time
  inDistance = inConstant ** time

  DEBUG HOME, DEC3 cmDistance, " cm"
  DEBUG CR, DEC3 inDistance, " in"

  PAUSE 100
LOOP

Tnx. Sorry 'bout that.

StormKing09

Can you give me some more examples plz. if so, tnx.

They're all available on the product page. I'm guessing that, for some reason, you have a download restriction. You'll want to find a way around that.

Good guess
