As shown in Table I, CEA curriculum was renovated in
2015 with additional class modules of Arduino and Android
App Development to provide more creative, interesting, and
challenging mobile projects to CEA students and to better
integrate activities of the first semester with mobile app
development classes in the second semester based on the
survey results after running CEA in 2013-14. Figure I
displays the snapshots of Android app created by
AppInventor to control LED lamp on Arduino board using
buttons on the touch screen and voice commands as an
example of activities.
