Arduino Nerf Target Alarm Clock

So you would like to build a clock that can be only silenced using a Nerf dart? Christopher Guichet has shared a video that shows his Arduino Nerf Target Alarm Clock. It uses a piezoelectric sensor to detect hits. In order to deactivate the clock, you will just have to shoot it.

The clock is driven by an Arduino Uno. It has a 3D printed housing printed using an Ultimaker 2+.  Yet another fun DIY project.
