Hi friends..
I would like to know if the above project uses PIC microcontroller or else.. That is important beacuse i m currently working on the project similar to that but implementing on a low level microcontroller AT89S51
So any body let me know plz,, which ucontroller it is using...
Thanks a lot...
What kind of sensor?
In past I did ultrasound range finder with PIC, but principle is the same. If you are using piezzo receiver and transmitter than you need to amplify the received signal and just send it trough ST to the µC. All the magic is in the time between sent pulse and received pulse. I figured out that pulse of 8 periods long is optimal for this kind of application.
