#1 about 2 min

Connecting hardware prototypes to the web browser

Web native APIs allow rapid iteration for building physical hardware controllers.

#2 about 4 min

Emulating computer keyboards with Arduino hardware boards

Specialized microcontrollers can automatically present themselves as human interface devices via USB.

#3 about 3 min

Programming keyboard emulation code with safety mechanisms

Implementing physical switches that write keystrokes requires emergency loops to prevent accidental system lockouts.

#4 about 3 min

Controlling the Chrome dinosaur game with physical prototypes

Aluminum foil pads function as basic hardware switches to trigger web browser events.

#5 about 3 min

Bidirectional hardware communication using the web USB API

Connecting directly over serial ports streams complex data between physical hardware and client applications.

#6 about 5 min

Processing serial data streams and building audio synthesizers

Line break transformers resolve chunked message errors for smooth sensor transmission to browser oscillators.

#7 about 4 min

Replacing complex wireless networking with web bluetooth connections

Generic attribute profiles enable direct low energy wireless linking between local prototypes and web applications.

#8 about 4 min

Advertising bluetooth services and parsing custom characteristic data

Implementing universal unique identifiers ensures web apps request and connect to correct custom hardware characteristics.

#9 about 2 min

Hardware recommendations and protocol compatibility for web interactions

Selecting specific electronic chip architectures determines whether devices support target peripheral logic and connection types.

#10 about 5 min

Exploring alternative microcontrollers and hardware material sourcing

Experience prototyping prioritizes affordable hardware boards over robust computing environments for rapid peripheral iteration.
