To demonstrate the concept, we use the apparatus in traditional experiments done in the physics classroom. We show that precise measurements can be obtained, making this apparatus a low-cost alternative to traditional photogate timers.engApparatusArduino boardHall effectMeasuring time intervals in the classroom with the Arduino board and a Hall effect sensorjournal articlehttps://doi.org/10.1088/1361-6552/ab26bf
