Folder Structure

The workspace contains several folders:

• src: Contains App.java and SensorArduinoCode.ino
• lib: Contains the jSerialComm.jar library used by App.java
• bin: Contains the generated compiled output files

About the Project:

I was fascinated by the idea of controlling mundane tasks on the computer without even touching it. Take for example, controlling the computer's volume, I thought it would be really cool to control the volume without touching the computer. To do that, I use one of the most recognizable sensors, which is the ultrasonic sensor.

How it works:

• When App.java is run, it will ask the user what they want to control: Volume, Page Scroll, or Tab Switching.

  Keywords:

  • "Volume" = Control volume
  • "Scroll" = Control Page Scrolling
  • "Switch" = Switch between Tabs
  • "End" = End any control

  Note: Capitalization does NOT matter

• If the user does not enter any of those keywords, App.java will keep on asking the user until the user gives one of those four keywords.
• Depending on the keyword, the state of the LEDs would change

  • "Volume" = RED on
  • "Scroll" = BLUE on
  • "Switch" = RED & BLUE on
  • "End" = RED & BLUE off

• When there's a change in distance, Arduino will send either 0 (denoting decreasing distance) or 1 (denoting increasing distance) to App.java. The code I've written here is using this rule:

  • "Volume": decrease distance(0) → decrease volume, increase distance(1) → increase volume
  • "Scroll": decrease distance(0) → scroll down, increase distance(1) → scroll up
  • "Switch": decrease distance(0) → switch to left tab, increase distance(1) → switch to right tab

  Feel free to change these settings as you wish
