# Servo Motor Control

Day 34 of the 100 Days 100 IoT Projects collection. Board: Pi Pico.

Position a servo precisely with PWM from the Pico 2W. The actuator behind robot arms and animatronics.

## How it works

The Pico 2W emits a 50 Hz PWM signal whose pulse width encodes the target angle — roughly one millisecond for one end, two for the other. The servo's internal controller drives its motor to that position and holds it against load. Precise angular positioning from a single wire.

## What you'll learn

- Servo control signals
- Pulse-width to angle mapping
- Holding torque concept
- Servo power requirements
