Description

We built a carnival-type game in which players have to hit a piece of cheese with a stuffed mouse. Foxes and cats are on the revolving sticks that prevent the mouse from getting to the cheese. If the mouse gets to the cheese, he wins, and lights go off and music plays. If he lands on the mousehole, he's safe, but he doesn't win.

Components Used

• 2 LEDs
• 2 FSRs
• 1 DC motor
• 4 chopsticks
• 1 potentiometer
• 1 diode
• 1 transmitter
• 2 10K resistors
• 2 220 resistors
• 1 buzzer
• a lot of wire
• a lot of tape
• cardboard
