This study aims to determine the feasibility of developing potential energy teaching aids based on the Arduino Uno microcontroller based on the assessment of media experts and material experts, the accuracy of the tool, as well as knowing the improvement of student achievement. The Arduino Uno microcontroller was developed with the help of ultrasonic sensors and load cell sensors. Student achievement in this study includes cognitive, affective and psychomotor. The model used in this study is the ADDIE model which consists of 4 stages, namely analysis, design, development, implementation, and evaluation. Based on the data analysis, it can be concluded that the validation of the Arduino Uno microcontroller-based physics learning teaching aids by two media experts obtained an average score of 95% in the "very feasible" category and by two material expert validators obtained an average percentage of 95.3% with the "very good" category. feasibleā, Accuracy of teaching aids physics based on Arduino Uno microcontroller. For the level of confidence in the measurement, the results obtained are 99.14% with an accuracy level of 0.86%. the average increase in student achievement in the cognitive domain is 14.8%, the affective domain is 8%, and the psychomotor domain is 18.3%. Thus, potential energy props based on the Arduino Uno microcontroller are feasible to be used as learning media in schools and are able to improve student achievement.
