The Rocket Game, like the projects requires the use of a USB cable to send digital information from four pushbutton switches to the computer screen. As shown in Figure 19-1, the breadboard circuit is quite simple to build and requires five 1KΩ fixed resistors and four pushbutton switches.
The basic digital circuit consists of a pushbutton switch and resistor wired in series. This wiring connection is repeated three times for the remaining switches. These switches are connected to pins D3 through D7 of the Arduino microcontroller.
The Rocket Game can be built using the Fritzing wiring diagram shown in Figure 19-2. The placement of the parts is not critical, so experiment with the location of the various electronic components, and the overall wiring of the device. One challenge is to wire all of the electronic components using the awesome (but kind of small) MakerShield protoboard. Can you fit it all on there?
