Summary:In this study, a kinetic friction coefficient was determined using an Arduino microcontroller. For this purpose, we used an Arduino UNO, an HC-SR04 ultrasonic distance sensor, two wooden blocks, a pulley system and connecting cables. In the experimental process, one wooden block was attached to another wooden block that was able move in the vertical direction with the help of a pulley. The acceleration was calculated by taking the change of the position of the object per unit of time with the help of a distance sensor throughout the movement. Then, using Newton's second law, the friction coefficient between the wooden block and the surface was calculated as 0.426. In order to test the accuracy of the study result, a widely used method was also used and the kinetic friction coefficient was found to be 0.384, which is close to the result determined in this study.
