Most button tutorials stop at detecting a press. Real projects need to know how a button was pressed — and they need that logic to stay clean as systems grow.

In this video, we revisit the Universal Button Library and build up from the simplest possible Arduino example to a scalable input architecture suitable for full ESP32 projects. Along the way, you’ll see how a single physical button can reliably generate short presses, long presses and double clicks — without cluttering your loop with timing logic or state machines.

You’ll learn how to:
✅ Define button behavior once at compile time
✅ Detect press types without delays or edge-case code
✅ Use named button intents instead of raw pin numbers
✅ Keep input handling clean and readable as projects scale
✅ Integrate buttons into a layered input → decision → execution system

We then apply the same patterns to a real Power Wheels rebuild, where button input is treated as just one source of intent alongside RC control and other inputs. By separating input handling from decision-making and execution, the system remains stable even as new buttons, press types, and devices are added.

This approach works equally well for Arduino sketches, ESP32 RTOS projects, robotics, and embedded control systems — and it scales without breaking existing code. All example sketches and supporting libraries are available on the Little Man Builds GitHub page (link below).
