Final Project Proposal

WHAC-A-MOLE

Concept:

For my final project I’m thinking of making a whac a mole video game stand where users can hit a mole that is showed in the screen but connected to the arduino board so that users can hit the physical mole that pops up on the screen. For the moment, I’m still thinking of my own creative twist for this project, but I really like the idea of physically hitting something that will connect a circuit through the board to make the system complete and score a point on p5js.

Implementation:

The user will see a couple of holes in the screen where a mole will pop up every now and then, and the user will have to hit the correlating sensor with a special hammer I will design that will finish the circuit, which will send a signal to the arduino board and will interpret as a “hit” of the mole and score a point. So basically the hammer is a big switch that the user must turn on precisely when the mole peaks its head out.
