ButtonHero
ButtonHero
by Brendan Ferracciolo and Daniel Mayers
Brief Description
ButtonHero is a game similar to guitar hero. To play you must hit the button the corresponds to the LED that lights up. The game is fully enclosed within a box made from a 3-D printer.
Detailed Description
ButtonHero is composed of four LEDs, four buttons, a screen, an Arduino Duemilanove, many resistors, wires, a 3-D printed box, and a prototyping shield. The program takes advantage of many If statements. All of the components are attached to the prototyping board which is connected to the Arduino. 8 digital pins are used from the Arduino along with the ground and +5 volt pins. The loop uses digitalRead() to look and see if a button has been pressed and stores this in a variable. This then checks to see if the correct button was pressed in which the code either contiunes the loop, adds a point, or detours to loseHealth() where one point is subtracted from the health and retrieves a new random seed for random(). With every 5-10 correct hits the timeout delay is shortened to make it harder and harder as the game progresses. The video below only shows the beginning due to an attempt at keeping the video fairly short, so it only demonstrates the easy beginning of the game..

Other
Some problems that we encountered were whenever the far right button was pressed the circuit shorted, this was fixed by removing a small piece of solder that was bridging across two pins. Also the hole for the screen was slightly too small and had to be enlarged with sand paper.
With more money we would have like to make the box a different color and slightly larger. Additionally, re-printing the back would have been useful if we had enough time as it did not fit correctly and had to be glued on instead of snapping in.
