Arduino project for catching my cats on the kitchen counter, while they’re up there doing food intelligence work 🙂
Arduino nano in iPod Touch box. Switch arms toy gun, Knob controls trigger distance. Opto-isolators fire toy gun.
Maxbotic ultrasonic rangefinder senses distance and determines if sonar field has been interrupted ( by cat). The gun just makes a silly little ‘p-tang’ sound and flashes a red LED in it’s barrel. The cats seem to completely ignore this 🙂
