Simple Compass App is Ready for Download

Sorry for late update. I am busy studying a electronic class and building simple circuits recently. All those electronic components are very interesting with their own personalities and functions like resistor, capacitor, diode, transistor, LED. It is fascinating that the combined components can do so many different tasks.

 



Back to the app development : ), the Simple Compass App is ready at Google Play for download:

It is a simple compass with the electromagnetic field strength displayed. The background electromagnetic field strength around us should be ~40 - 60 uT. If it exceeds that range, the compass app will probably not functioning correctly. Besides, the app provide some educational information regarding electromagnetism on the Earth.
