Mobile physics education lab (easy measurement of speed and acceleration using ultrasonic sensors)

・ This application connects the ultrasonic sensor unit product researched and developed by the mobile physics education lab (Diracma project) to the smartphone and measures speed and acceleration easily.

・ Please refer to the Diracma project site for product purchases and experimental data (https://sites.google.com/view/diracma888/).

・ Please refer to the video of the experiment example using this application (https://youtu.be/gpoTYiuF6cc)

-Diracma is on the left of the application icon and Micolo is on the right, which represents that external information is obtained via a microcomputer.

-First, the time change of the distance is displayed.

-When the Graph button is selected, the time change of speed and acceleration is also displayed (including the menu function, an optional function dedicated to ultrasonic sensor products).

-The time, distance, speed, and acceleration values ​​at the point where the screen was touched are displayed.

-The graph on the screen can be enlarged and moved by touch and slide.

(Chart uses MpAndroidChartlibrary library)

・ To restart measurement, press the Restart button.

・ In addition to the Diracma series for physics experiments developed by the project, there are DiracmaA and DiracmaJump for dynamics experiments and DiracmaS for sonic experiments. .com / view / diracma888).
