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 :)
