Inspiration

We wanted a more convenient way to control home appliances without needing to get up, and realized this could also greatly benefit users with limited mobility or physical disabilities.

What it does

Lil Ghost is a smart home system that uses gesture recognition to control appliances like lights, thermostats, and door locks, with real-time feedback via a web interface.

How we built it

We used an ESP32 with an IMU to capture gestures and send data to a React/Next.js web server, which then communicates with an Arduino over USB to simulate appliance responses.

Challenges we ran into

Our second Arduino lacked Wi-Fi, requiring USB serial communication, which added complexity. We also had to creatively work around hardware limitations using software-based solutions.

Accomplishments that we're proud of

We successfully integrated gesture-based control with a full-stack system, learned multiple new technologies, and adapted quickly to hardware constraints.
