For many of us, traditional alarm clocks have given way to smartphones, but the concept is still the same: an annoying sound, followed by either waking up, or hitting the virtual snooze button just… one… more… time. On the other hand, when this alarm goes off, you need to shoot it with a Nerf gun in order to silence it.
The alarm/target works using a piezoelectric sensor attached to the clock’s housing. When the alarm sounds, if it senses a dart hit by counting the signal pulses generated, it turns off. Ingeniously, and perhaps annoyingly, it can tell if it’s tapped by a finger, and not respond accordingly!
Each Monday is ArduinoMonday here at Adafruit! Be sure to check out our posts, tutorials and new Arduino related products. Adafruit manufactures the Arduino right here in the United States in cooperation with arduino.cc. We have a huge selection of Arduino accessories and all the code and tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
