Description:
For this project, I aimed to create an interactive 8-bit type representation of a house that the user could interact with and change stuff about their environment with the interface. I decided to go with lights and represent their states in the virtual p5.js environment. The user can click the lamps in the virtual world and turn them on/off in the real world. The states of the lamps are reflected in the p5.js environment as well brightening up the surrounding environment when they are on. The user can also turn the lights on and off in the physical world and the light states would be again reflected in the virtual environment so the information goes both ways from p5.js to arduino and back.
