Good day to everyone. I would like to know if anyone has any experience and can give me an example of using flowcode to capture and store the distance readings from a Polaroid 6500 Ranging Module. Or any distance ranging unit. Thanks in advance.

Hello,

I have no experience of using this module, but it looks similar in operation to the one we sell.

Basically, you send a pulse to it and then read the echo-ed pulse back. The pulse transmits sound (at the speed of sound) which bounces off the target and returns to the transducer. By monitoring the time taken to receive the pulse, you can calculate the distance travelled.

I did a web search and this link has more details:

I don't have any sample code to hand.

Thanks Steve. I read through it, would like to get some flowcode examples, I"ll try working through it and see how I make out.
