This study aims to determine the feasibility and accuracy of dynamic fluid practicum tools (Torricelli theory) based on Arduino Uno. This is a research and development (R&D) by adopting the development steps by Richey and Klein, namely PPE (Planning, Production, and Evaluation). The research flow consisted of a problem and needs analysis, planning, manufacturing, initial testing, product validation, product revision, and final testing as well as teacher and student assessment of grade 11 MA Salafiyah Asy-Syafi’iyah Jatirogo. The data collection techniques used were interviews, material, and media expert validation questionnaires, physics teacher responses, and student responses. Feasibility can be seen through the results of validation by material and media expert validators, then the results of accuracy can be seen by comparing the values read on the product with the theoretical values, in this case, the gravitational acceleration value of 9.8 m/s2 is used. Based on the data analysis, it was concluded that the practicum tool developed had very feasible criteria with a percentage value of 93.33% by material and media expert validators. The final test results to determine the accuracy of the practicum tool by comparing the readable value with the theoretical value, obtained a percentage of 95.82%. Teacher and student responses to practicum tools were obtained by a percentage of 94% by teachers and 91% by students with very positive categories.
