Hello sir, ive made your project and it was working well. But i only have one problem, every time i pressed the button to register new pattern, it automatically knocks by itself. It knocks 10 times straight. Hoping for your fast reply! :) Thankyou.
Knock box (it opens when you knock on it!)
How can i use the sensor as a buzzer too?
Hello sir, nice circuit. What piezo have you use? Piezo buzzer or piezo sensor? Thankyou!
I need your reply sir. Hehe
Im gonna do this for our thesis. What sensor have you use from the below? i dont know what kind of piezo to buy. Thank you in advance!
Hi, thank you! I just tried to open the link in the instructable, and it worked for me.It's this one: http://pastebin.com/9mDBrR0DMaybe you have some connection issues?Let me know if you have other problems.
Tuixte, that is a great idea and i was making the circuit and when the time to upload the code to the arduino came what was my surprise, i cant download the code, can you upload the code again please?---Sorry for the bad english
Heres the piezo sensor im talking about
Thank you for the fast reply. I think ill be sticking on using piezo sensor, im still not good at making codes.The piezo sensor i saw is (https://josephmalloch.files.wordpress.com/2010/01/... like this? It doesnt have buzzer right? heheAnd about the servo, i still dont get it. I dont know what's the use of the hole in the picture for the servo. Sorry its my first time to use arduino and servo, to make something like this.
Sir how is the position of the servo in the box, so that it can open? And what if i only have a piezo sensor, how can i add a buzzer? Many thanks for your reply :)
Hi! For the piezo, it is just fine, you can use the sensor as a buzzer too. I glued the servo in the box, and a piece of metal with a hole in it, on the top. In this way, when the servo moves, the white end goes into the hole, closing the box.Anyway, I made another version of this box, using a capacitive sensor instead of a piezo (you can just use a piece of aluminium paper, attaching a wire to it). If you can do it - it only requires a few changes in the code - it's a lot more efficient sensing the user's touches!
