This study focuses on the design, development, and evaluation of an
Intelligent Cat Feeder aimed at addressing the inefficiency of manual
pet feeding systems. The primary objective of this project is to
construct an automated device that delivers superior feeding
convenience and efficiency compared to conventional methods. By
leveraging an infrared (IR) receiver module combined with an Arduino
microcontroller, the device enables users to easily control the food
dispensing process remotely via an IR remote control. During the
development phase, key operational challenges were identified,
including the accuracy of the food dispensing mechanism, the
stability of the combined frame structure, and the essential need for
regular maintenance to maintain food container hygiene.
The product was developed by integrating electronic components
(Arduino microcontroller, IR receiver module, and servo motor) with a
creative physical structure using recycled and readily available
materials. Two tin cans are assembled vertically as the main food
hopper structure; the upper tin (wrapped with a black sticker) serves
as the food storage container, while the lower tin houses the servo
motor and acts as the food dispensing pathway. An electric junction
box is used as the main enclosure at the back to securely and neatly
house the Arduino circuit board and wiring. Blue impra board and
cardboard are used to construct the hopper stabilizing structure and
the food output chute, while a 15cm wooden stick is installed
vertically at the base as a upright support structure to ensure the
entire device stands upright, stable, and sturdy. The servo motor
controlled dispensing mechanism requires periodic maintenance to
prevent food blockages and maintain optimal operational efficiency.
The Intelligent Cat Feeder successfully provides effective pet feeding
functions that are easier to control using an IR remote compared to
manual methods. However, testing revealed operational constraints,
including food portioning accuracy depending on the servo motor
angle and tin passage clearance, the long-term structural stability of
the materials against the weight of the food, and the risk of food
blockages if the output chute is not regularly cleaned.
In conclusion, the Intelligent Cat Feeder effectively achieves its core
objectives using Arduino components, an IR module, a servo motor,
and a practical combination of materials such as two tin cans (as a
food container and servo housing), an electric junction box, impra
board, cardboard, and a 15cm vertical wooden support stick at the
base. To improve future iterations, it is recommended to integrate a
Bluetooth module (such as HC-05) or a Wi-Fi module (such as
ESP8266/ESP32) so that the food dispensing system can be
controlled directly via a smartphone application (such as Blynk),
alongside adding a Real-Time Clock (RTC) module for automated
scheduling and upgrading the structure to more durable materials.
