This puzzle box uses an arduino as mechanism. a few different sensors, buttons and lights will make sure nobody will be able to open this box. In order to open this box you first have to hold the box at a distance of 100 to 110 centimeters above a wall. then you'll have to reflect a laser on a sensor. Than you'll have to cover two light sensors. as last you'll have to whistle a specific tone after that you'll only have to push a button and a small motor will open the box.
mind blowing arduino puzzle box (with electronics)
this box is really hard to open, and it's quite complicated
