+# Servo Motor Component
+
+This component provides an easy-to-use interface for controlling servo motors with the ESP-IDF framework. Servo motors are commonly used in robotics, automation, and various mechanical applications due to their precise control of angular position.
+
+The library uses PWM (Pulse Width Modulation) to control servo motor rotation and supports customizable configurations for angle limits, pulse width, frequency, and more.
+
+## Features
+
+- Easy control of servo motors using PWM signals
+- Support for custom angle range and pulse width
+- Flexible configuration of PWM channels and timers
+- Compatible with the ESP-IDF framework
+
+## Getting Started
+
+### Prerequisites
+
+- ESP-IDF installed and configured on your development environment
+- A servo motor compatible with PWM signals
+- Proper connections between the ESP32 and the servo motor (signal, VCC, GND)
+
+## How to use
+
+Initialize the sensor with the configuration:
+
+```c
+    servo_config_t servo_cfg = {
+        .max_angle = 180,
+        .min_width_us = 500,
+        .max_width_us = 2500,
+        .freq = 50,
+        .timer_number = LEDC_TIMER_0,
+        .channels = {
+            .servo_pin = {
+                SERVO_GPIO,
+            },
+            .ch = {
+                LEDC_CHANNEL_0,
+            },
+        },
+        .channel_number = 1,
+    };
+
+    // Initialize the servo
+    iot_servo_init(LEDC_LOW_SPEED_MODE, &servo_cfg);
+```
+
+Set the angle:
+
+```c
+uint16_t angle = 0;
+iot_servo_write_angle(LEDC_LOW_SPEED_MODE, 0, angle);
+```
