Scroll Menu

Scroll Menu with multiple functions, where with every functions you can set up certain things. Example: Changing Alarm Time Changing volume

The reason I made this, is because I don't want to use the raspberry pi only for just 1 thing. I want to use it for multiple script and don't want to use a command section to get the other script to work. Here I can also put all my future projects in.

First mission is to make it possible that it goes up and down in the menu and than choose a certain function.

• 1. Select option 1
• 2. Select option 2
• 3. go to the begin of the menu
• 4. Go to the End of the menu
• 5. Going down in the menu
• 6. Going up in the menu

For this script I used previous scripts that I already made in previous blogs.
