Sonar Flap (ultrasonic) - a Basys 3 game for Virtual Basys 3

How to play: Your hand height over the ultrasonic sensor sets the bird's height: drag the distance slider (or the sensor card). btnC starts. sw0 = distance on the 7-segment display, sw1 = easy mode.

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.
