One project I have recently worked on in Code.org is a project involving the creation of multi-screen apps. In this process I used a combination of event handling and event-driven programs to create a multi-screen app that has no dead ends and has a functional use. The code that went into the making of this app was relatively simple. It involved using functions to transfer screens or play sounds when a button assigned to the function or sound was pressed.
Pictured above is the sound board app that I created. Check it out with the link posted below
