This one-page web application is a basic timer/sequencer which can load a list of events ordered by time (mm:ss) from an “[login to view URL]” CSV file when the page is initialized. When the user selects a Play function, the application starts a timer and cycles through the list of events. Then the timer matches an event time, the application executes (1) a display message or (2) a play sound behavior and updates the application page display objects. There are two parts to this project, the web application (using Python, PHP or Node.js) and a small Python program (Python 3+). The web application can call the Python program to play sounds depending on settings as described.
