Web Servo Controller
Motors · Board: Pi Pico · Day 14 of 100
Drag a slider in your browser to swing a servo from 0 to 180 degrees over Wi-Fi on the Pico 2W. Web UI meets precise motor positioning.
How it works
A slider on a web page sends the chosen angle to the Pico W over Wi-Fi. The board converts the angle into the corresponding control pulse width and outputs it as PWM. The servo's internal circuitry then rotates its shaft to match and holds position.
What you'll learn
- Servo pulse-width control
- HTTP control endpoints
- Angle-to-pulse mapping
- Browser-based actuation UI
