You will need space to place the electronic components and the food inside. I used a square box, but you may use a cylinder like in the original tutorial (the square box made it easier for me to place the components inside). Look for something no less than 12 inches tall. A cardboard box: Do not underestimate the height.

Folding utility knife: I used this to cut holes that were too small for scissors.

Glue gun: Any glue gun will do there's no need to get something fancy.

SG90 9g micro servo: This opens and closes the trap door inside the food dispenser.

We plan to do other projects with some of the pieces in the box.

Smraza basic starter kit for Arduino: This starter kit includes the power supply and breadboard to connect the Arduino with other components.

ACEIRMC HC-SR04 ultrasonic sensor distance module: This detects if a pet is in front of the dispenser, and if true, dispenses the food.

Chanzon 9v battery clip: This connects a 5V battery to our Arduino, so it can run without being attached to the computer through the USB cable.

Arduino Nano : This is the brain of the project. We chose this model due to its price and size.

I do not get a commission, and I encourage you to look around for the best price.
