Scaffolding Mapping - Fishing Game

 For our project we made a small interactive fishing game. The red light represents the fish, and other blue light represents the fishing hook. The player uses the potentiometer to move the hook across the board. When the hook lines up with the fish, it will turn purple and the player presses a button to catch it. The goal is for the player to guide the fish back to the starting position without losing it. If a loud noise is made, the fish will get scared and will respawn somewhere else, this adds some challenge and makes the experience feel more realistic.
