This demo describes how to make a smart pet feeder with the Tuya Sandwich development kit. The designed functions of smart feeders are as follows:
It is an easy demo for making a smart product prototype without complicated hardware design. You can use corrugated cardboard as the feeder shell in the first place and replace it with your required structure and material such as a transparent acrylic board.
Power other components of the Tuya Sandwich Evaluation Kit.more
Widely apply to prototypes developed by Tuya IoT custom solutions, including lighting, desk lamps, filament lamps, dimmers, lighting remote controls, power strips, switches, home appliances, exercise and health, and sensors.more
Provide torque for smart pet feeder.
An embedded development board that can be used to try innovative prototypes by combining different functionalities and consumption features provided by STM32 MCU.
Make a regular hexagonal rotating wheel with ice cream sticks. For better fixation, you can use a plastic bottle cap as a support, so that the screw can bite into the middle to connect with the motor, and the surrounding space can be glued and fixed later.
The maximum diameter of the rotating wheel is 7.5 cm, which is equivalent to the inner diameter of a circular tape.
The height of the ring of the rotating wheel is 1.5 cm. You can cut the circular tape to make a ring for backup.
You can make four isosceles trapezoids with the height, top, and bottom sides of 10 cm, 10 cm, and 20 cm respectively, and assemble them into a food tank.
Prepare a 10 cm square and cut a 120° fan shape with a diameter of 7.5 cm in the middle as the bottom seal of the food tank.
Prepare a 20 cm square and cut a 120° fan shape in the middle. Cut a round shape according to the motor column size to place the motor.
Make a motor bracket for core components assembly, and fix the rotating wheel with screws on it. Then place the food tank on the top thereby completing the core structure. Make a channel at the bottom as the food tray. You can postpone fixation for the convenience of subsequent debugging.
Prepare a Sandwich development board and a computer with a Windows operating system.
Write the embedded program code according to the product functions and attributes you selected.
See the section Burning firmware and authorization in Prototype a Smart Light, and burn firmware to the Wi-Fi development board.
You can use plastic bullets as cat food for food loading test.
(Optional) Adjust the height of the food tank as needed.
Put up the shell after assembly.
Download the Tuya Smart app to your phone.
Open the Tuya Smart app, add your device, and find your pet feeder.
Start network pairing based on the program embedded.
Complete the following steps as per the prompts.
Try controlling the pet feeder with the Tuya Smart app.
The biggest concern when you are off home for a long time is your pet. You can create an economical and practical smart pet feeder on the Tuya IoT Platform to enable remote feeding control. For more information, see Tuya Solution Center.
