-===== How to... ===== 
  
 +===== Download and Launch the Nexys 4 Out of Box Demo =====
  
 +>Follow the [[:learn:programmable-logic:tutorials:github-demos:start:|Using Digilent Github Demo Projects]] Tutorial. This is an HDL design project, and as such does not support Vivado SDK. Select the tutorial options appropriate for a Vivado-only design. As you can connect your mouse, monitor, or audio output device to your Nexys 4 after the demo is running, you do not need to return to this guide when prompted to check for additional hardware requirements and setup.
  
-==== 1. Generate the Project ====+===== Using the Nexys 4  Project =====
  
->1.1) Download the repository linked in the download section and unzip it in the location of your choosing. +This portion will help you run the demo and observe all its features.
  
->1.2) Generate the **User_Demo** project in the Projects folder by following this guide before continuing: [[vivado:github|How to Generate a Project from Digilent's Github]]+==== 1. Using the Switches with LEDs ====
  
-==== 2. Build the Project ==== +>For this section, all the switches are tied to their corresponding LED. Every time a switch is toggled, the LED directly above it will toggle with it. If the center push button is pressed, all the LEDs will be tied to ground

->2.1) Click **Generate Bitstream** on the left hand menu towards the bottom. Vivado will run through both Run Synthesis and Run Implementation before it generates the bitstream automatically. +

-==== 4. Run the Project ==== +>The two tri-color LEDs are initially set to gradually change from red to green, then green to blue, then back to red. If the user pushed btnR, the LEDs are set to blue. If the user pushed btnC, the LEDs are set to green. If the user pushed btnL, the LEDs are set to red. Finally if the user pushed btnD, the LEDs return to their gradual change loop. If the user keeps pushing btnD, both LEDs will be isolated then both will be turned off.
