Applications of the Arduino Electronics in the Kinematics

Abstract

Due to high precision, quick response and low price, Arduino electronics, including motherboards and sensors, have potential to be the main parts of physical experiments. Especially, the experimental data can be easily transferred to smartphones and tablets through the Bluetooth communication that greatly enhances the portability of the experimental equipment. There are many commercially available detectors compatible with the Arduino motherboards such as the DHT11 which is for the humidity and temperature detection. For the detection of linear and rotational motions, ultrasonic sensor and photoelectric switch will be good choices.Here, we demonstrated controllable damping and force oscillations in a spring-mass system. The motion of the oscillator was detected by an ultrasonic position sensor. The damping and driving forces were provided by the coupling between a electromagnet and the permanent magnet mounted on the oscillator. By tuning of the strength of the electromagnetic field, the damping constant can be manipulated. The accomplishment of the force oscillation was made by exertion of the driving force as the oscillator rebounded. All of the motion detection and the signal access were based on the Arduino sensors and electronics. This shows that Arduino electronics can replace the expensive equipment for the kinematic experiments.
