# Key Value **Tier:** 1-Beginner Have you ever thought about what it means that the computer you are using is a digital device? Among other things it means that everything its capable of is achieved by translating a digital signal into a sequence of binary digits - 0's and 1's. These binary digits form codes used to represent data. The keyboard you used to retrieve this project description is a great example of this. Pressing a key generates a digital signal that is translated by the computer into a code representing the key that was pressed. The goal of the Key Value app is to display the encoded value on screen each time a key is pressed on the keyboard. ## User Stories - [ ] User can see a display panel containing a text area where the key value and key code will be displayed along with display areas for four other indicators related to the keys on the keyboard - alt key, control key, meta key, and shift key. - [ ] User can see the key code and key value displayed in the display panel corresponding to the key when it is pressed. - [ ] User can see the appropriate indicator change from 'False' to 'True' when the alt, control, meta, or shift key is pressed. ## Bonus features - [ ] User can hear a unique tone played when a key is pressed. - [ ] User can see the background color of the key code and value change when a key is pressed. ## Useful links and resources - [Digital Electronics](https://en.wikipedia.org/wiki/Digital_electronics) - [Keyboard Event](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent) ## Example projects [Javascript Keyevent Test Script](https://unixpapa.com/js/testkey.html)
