WebSerial Microcontroller Interaction

Definition

The use of the browser WebSerial API to establish bidirectional, low-latency serial communication between web applications and physical microcontroller boards (ESP32, Arduino, XIAO).

Key Characteristics

• Direct hardware connection without native driver installation or intermediate server bridges.
• Streaming high-bandwidth sensor data, camera frames, and machine learning inferences into web UIs.
• Interactive calibration, firmware parameter tuning, and hardware actuation directly from web apps.

Applications

• Physical computing studios (DDA647/DDA657)
• Interactive browser installations
• TinyML prototyping
