PENGEMBANGAN MEDIA PEMBELAJARAN KONTROL KECEPATAN MOTOR DC BERBASIS ARDUINO DAN VISUALISASI DATA MENGGUNAKAN HUMAN MACHINE INTERFACE(HMI)

In the digital and modern industrial era, mastering motor control technology is important. The goal of this study is to develop interactive learning media that combines Arduino Uno, rotary encoder sensors, BTS7960 motor drivers, and Nextion human-machine interface (HMI) technology. The system is designed to automatically regulate the speed of a direct current (DC) motor using a proportional, integral, derivative (PID) algorithm in a closed-loop control system.
The design involved building integrated hardware and software. The Arduino receives setpoint values from the Human-Machine Interface (HMI), reads the actual speed through sensors, and calculates errors in order to generate Pulse Width Modulation (PWM) signals that control the motor. The RPM value is visualized in graph form on the HMI screen in real time. Testing with varying loads was conducted to assess the system's adaptability and stability.
The test results demonstrate that the system can maintain a stable motor speed despite changes in the load. The HMI makes it easy for users to monitor and control the system. In conclusion, this learning media is effective in electronics engineering education and can be applied to small-scale automation systems.
