I believe that every dog owner has the same frustrations of your dog digging in the trash even with a trash can lid. So I want to adjust my dog’s behavior by designing a trash can with a sensor that makes a buzzing noise to stop them before they start their “treasure hunt”.
I realize that most trash cans are in a cylinder shape where my dog loves to approach it from all directions which would be hard to capture their coming distance, so I want to make a right triangle shape trash can that can be placed in a corner of my home, and the sensor will be on the hypotenuse side to better measure and capture my dog’s movement.
- The trash can will be constructed based on three main pieces of acrylic sheets, so measure and cut the neopixel strip based on the acrylic sheet’s length.
- Solder the Neopixel strip, buzzer, and ultrasonic sensor onto an arduino board.
- Alter the code into white color light.
- Set the buzz time to last 3 seconds.
- Cut a slit (that would fit the neopixel strip) in three wooden blocks
- Cut the wood diagonally on the two shorter sides of the wooden block
- Cut the plywood into right triangle shape as the trashcan’s base
- Glue all the parts together
