Secret Door knock

[kerem sekerci]

Hello,

Just wondering if anyone here can build a secret door knock Arduino, or whether they know anyone that can build one? 

I'm after a price for parts and labour, it's just for a personal project. A rough estimate would be enough. 

Here's a reference:

Thanks.

Hi there

We aren't really for hire, although if a member wants to step forward to offer to build it for you that's their call. Why not build one yourself? :) The guy in the video you linked shared his arduino code on the instructables:

Or, you can sign up to his mailing list and buy one when he sorts out putting a kit together:

Cheers,

arduino uno.. $4 from aliexpress.. delivered
piezo transducer.. ~$2


i built this project once, wasn't quite the secret door knock rhythm
code, i only bothered to detect 1 knock.
but all the code for that is fairly trivial... just have to add a small
buffer of the last 5 knock times, and if they fall within the rhythm
pattern, then turn on a output pin.

Yes I should. I've just had Arduino troubles in the past, would rather it be bullet proof and built by a professional :)
