Electronic Desktop Dispenser

Turn a wave of your hand into a little bit of magic with this 3D-printable automatic dispenser! An ultrasonic sensor detects when your hand is nearby and activates the internal mechanism to release a container through the front opening. Powered by an Arduino and stepper motor, the dispenser can be customized with adjustable activation distance, sensitivity, and motor speed, making it a fun and functional electronics project for your desk, workshop, or game room.
