Arduino uno User Manual

Figure 27—Circuit of our video game console
The player controls crosshairs using the
Nunchuk’s analog stick and has to shoot
circles using the Nunchuk’s Z button. The
circles appear at random positions and
stay there for 1.5 seconds. A status bar
at the top of the screen shows how much
time is left until the current circle disap-
pears. The game ends after ten rounds,
and the game’s goal is to hit as many cir-
cles as possible.
