PIC 16F877A Based Sonar

[lupifieri]

Do you still having the Code for it?

@lupifieri Please check out the info on the video...

brother can u help me with my final year sonar detection system pls?..i m getting many difficulties in tat pro

[technoshamanarchist]

@EE061003 Google for acroname and robotelectronics uk for example code and schematics. Those are what I used...

[faixal117]

Boss...i like ur post...

plz...can u giv me this c program coding...

[jmyk007]

wanna try to build dis one.. dis is a 10 thumbs up! can u please send it to me schematics and codes.. plz!

The LCD LED is fading when your hand is in proximity to the sensor, you need MORE POWEEERRR

[technoshamanarchist]

That was 3 years ago with a bad wall wart power supply :) And as you see it ain't a real project on a PCB. Check out my other projects if you want. I don't see a project of your own on your page ;)

Hello,it is really amazing and interesting what you have done,am new to ultrasonic sensor,can you send me your code,am using a PIC16F877 with a 4 MHz crystal instead of PIC16F877A i need to understand how it works,

[schnuber]

Hi

U can measure distance with ur sonar system? What accuracy does it have? what frequency do u use for ultrasound?

greets

[technoshamanarchist]

Yes you can... HYDRA uses the same system for navigation. The one I made is precise to a cm, but I think you can do better than that if you tweak it. The SRF05 is a module with its own MCU, and it uses 40KHz pulses.

[schnuber]

Can you please test whether you can not only detect the distance to your hand but also to a thin foil, e.g some general plastic foil

[technoshamanarchist]

Yes, anything from a tin box to a live cat :P

[technoshamanarchist]

People who like this project should give some stars :P No stars no code or schematics ;)

[Xuan1985]

i give 5 stars d! haha! can send me the code n schematics?

[technoshamanarchist]

mail me your mail :)

[Xuan1985]

hi technoshamanarchist, i m currently doing this sonar project oso, n i would like to add another pair of ultrasonic sensor like urs, but i face some problem in my code. Can u plz send ur code n ur circuit to me for reference? Thx u 1st!

[nicklooi]

hi, ur project was awesome..

can u teach me built 1 of this??/

or guide me or sent me the circuit diagram ???

or anything that might help??

please..!!!

I would appreciate it if u sent it to me 。。。

can v be frien?? cz m admire ur knowledge.. hope tat v can be frien

[technoshamanarchist]

Thansk, but this was not a project, just testing the SRF's. Messasge me your e-mail, and I'll send you the code for it... you don't need that much of a hardware as long as you own one of these modules...

[barryforever]

hi men ..

well im working on UAV and i need to know what kind of ultrasonic trasnducer you used

[technoshamanarchist]

srf04 and srf05 find devantech on google ;)

[farad007]

Well, in college i studies about pic mcu and its architecture but we did really go indepth. So, it has been 3 years now since last studied pic. But i did most of the programming in asm. And ya i would appreciate if you can send me tutorials on how to program in c and anything that u think will be helpful. :) cheers!!!

[technoshamanarchist]

Oh, ok cool :) Message me here your e-mail address, and MSN if you have it... let's keep in touch :)

[technoshamanarchist]

Most E-Engineers agree that unless you're gonna pregram a missile guidance system, C is as good as ASM, and saves you a lotta time and hair on your head :P I dunno how experienced you're with PIC's, but it'd be a pleasure to help you if you decide to program in Hitech PIC C.

[farad007]

Nice, i do my stuff with asm though :). Im working on a project [IR rx and tx] so far i got my lcd initialized .. :*(

[farad007]

sweet project! did u use assembler or c coding?

[technoshamanarchist]

Thanks :) Too lazy for assembly, and Hitech PIC C (ANSI C) is pretty low level anyway...
