A straightforward countdown timer application developed using MIT App Inventor. Set your desired time, start the countdown, and get notified with a sound when it finishes or is stopped.
The Simple Countdown Timer app provides a clear interface to manage a countdown. It's useful for simple timing tasks where you need a visual countdown and an audio alert at the end.
- Set Time: Adjust the countdown duration using "+" and "-" buttons.
- Start Timer: Begin the countdown from the set value.
- Stop Timer: Pause or stop the countdown at any time.
- Countdown Display: Shows the remaining time in a text box.
- Audio Notification: Plays a sound when the timer reaches zero or is stopped.
To build and run this application, you will need:
- An account on the MIT App Inventor website (appinventor.mit.edu).
- A computer with internet access.
- An Android device or emulator for testing the application.
- A sound file (e.g.,
.mp3,.wav) to be played when the timer finishes or stops. Upload this file to the Media section in the Designer.
Refer to the step-to-step_guide.md file for detailed instructions on how to recreate this application in MIT App Inventor.
- Launch the application on your Android device.
- Use the + and - buttons to set the desired countdown time in the text box. Each click adds or subtracts 1 unit (assuming the units are seconds based on typical timer behavior, though not explicitly defined in the blocks).
- Tap the Start button to begin the countdown.
- The number in the text box will decrease.
- Tap the Stop button to pause or stop the timer. A sound will play.
- When the countdown reaches zero, the timer will stop automatically, and a sound will play.
This application was built using the MIT App Inventor platform (appinventor.mit.edu) and utilizes the Clock and Sound components.
