I need Digital Mdf project

You waste your time and money on unstable 555. You do not understand this is obsolete.

Ok, lets say me stable one .

[Mike(Mont)]

Your choice. Sorry for trying to help.

[Mike(Mont)]

Forgive me for being so slow. Yes. your device when set to 700Hz will do very well at finding an empty hole.

[Mike(Mont)]

If you get a cheap frequency generator with a frequency counter function you could hook it up to your 555 and set the frequency to 700Hz.

[wtrk]

Hole Frequency is ok..
But this device should be set 4-5 different mode..
My friends programmed it like below in video.

also I have code.

[Mike(Mont)]

Must be some kind of language barrier here.

[wtrk]

Its Turkish language..
Altın : Gold 5.25 khz
Gümüs : Silver 8.95 khz
Kursun : Lead 4.25 khz

Like this.

[Mike(Mont)]

Sounds like that will work much better than the cheap Chinese stuff. Save a lot of money, too. The time it takes to build it is free, too!

So at the attachment is Proteus 8 file.

Many circuits have been made to produce a signal
Well is not alone digital signal generators for Search
Because the square and sinusoidal signal search should be used at the same time to lower the error
Let's share your hex file you want to work.
