Abstract

This study reports exploratory development and preliminary static-distance testing of a prototype using a DFRobot TF Mini LiDAR ToF Laser Range Sensor (SKU SEN0259), Arduino Uno, and a 16 × 2 LCD. The development narrative is organized with reference to the ADDIE framework (Branch, 2009). During the International PPL (Praktik Pengalaman Lapangan) program at Sangkhom Islam Wittaya School, Thailand, the presenter introduced basic motion concepts and the sensor’s operating principle, then demonstrated the prototype by pushing an object toward the sensor. Although the display was intended to show distance, velocity, elapsed time, and acceleration, only static distance readings were available for analysis. Five readings were recorded at each nominal reference distance of 100, 150, 200, 250, and 300 cm. The overall mean absolute error was 16.68 cm and the root-mean-square error was 20.80 cm. The results indicate that calibration and controlled testing are required before the device’s dynamic outputs can be validated. No standardized teacher-evaluation instrument or student learning-outcome data were available; therefore, the findings are limited to the prototype and preliminary static readings.
