What do people build with it?

USE CASE 1

Build a robotic head that mirrors a person's facial expressions in real time.

USE CASE 2

Make an LED display change based on how big someone's smile is.

USE CASE 3

Create a game controller where facial movements are the input instead of buttons.

USE CASE 4

Add face-tracking control to an interactive art installation without building computer vision from scratch.

What is it built with?

Copy-paste prompts

Prompt 1
Show me how to receive facial expression data from this Arduino library and use it to control a servo motor.
Prompt 2
Explain how this library bridges a phone's face-tracking app with Arduino hardware over serial or wireless connection.
Prompt 3
Adapt this library so an LED display brightness reacts to smile intensity detected by the phone app.
Prompt 4
Walk me through setting up this Arduino library since the README doesn't go into detail on installation.
