Description

This paper presents a further development of a so-called Ticker, a device supporting "hear and see" activity in classroom or laboratory exercises. While the original version of Ticker performs as a timing device, a new version of Ticker is improved in the sense of fast and wireless timing device. This wireless version provides the flexibility of measurements in various physics problems. The wireless ticker composes of a photodiode, a simple circuit, a wireless transmitter and a buzzer. The photodiode is equipped to enable the fast rise time. The ticker is operated by the change of intensity of the detected light on its photodiode. The simple circuit sends the signal through the transmitter while the wireless receiver is connected to a personal computer. Our developed software can be used to analyze the received signal. This new features of the ticker are meant to fulfill challenges in various teaching environments. The wireless ticker can also generate the ticking sound that aims to accommodate students with visual impairments. The experiments on simple harmonics, simple pendulum and acceleration have been performed as examples to show the capability of the wireless ticker. The demonstration shows the promise of the wireless ticker as a new teaching tool. This economic device allows a huge room for creativity with simplicity of reliable measurements.
