Hand Pong (ultrasonic) - a Basys 3 game for Virtual Basys 3

How to play: Your paddle follows your hand above the ultrasonic sensor (5-45 cm): move the distance slider. First to 7 beats the computer. No sensor: sw15 on, then btnU / btnD. btnC = new game.

This folder is a complete project: the Verilog (or VHDL) files and the .xdc pin file.
Read it in any text editor, or open it in Vivado and program a real Basys 3.

Change it and run your version:
 1. Edit the .v / .vhd files (for example colours, speed, the text on the screen).
 2. Open the simulator page and drop this folder on it ("Your project").
    Your own projects run on the free Virtual Basys 3 program (download it from the same page).
 3. Fix any error the build log shows, save, and drop the folder again.

vb3_core.v, vb3_text.v and vb3_sensors.v are small helper modules (VGA timing, text,
7-segment display, sensors) that you can use in your own games too.
