Master Arduino Control Servo Motors with HW-201 IR Obstacle Sensor – Complete Tutorial
Master Arduino: Control Servo Motors with HW-201 IR Obstacle Sensor – Complete Tutorial If you're diving into the world of Arduino and robotics, mastering the ability to control servo motors based on sensor inputs is a key skill. In this tutorial, we’ll guide you step-by-step on how to control servo motors using the HW-201 IR Obstacle Sensor with Arduino. This project will teach you the fundamentals of sensor-based motor control and can serve as the foundation for creating smart systems in various applications, like obstacle avoidance in robots. What You’ll Need: Before we get started, make sure you have the following components: Arduino Board (Uno, Nano, or Mega) Servo Motor (any standard 9g or 180° servo will work) HW-201 IR Obstacle Sensor Jumper Wires Breadboard (optional for organization) Arduino IDE (installed on your computer) Power Supply for the servo (if needed) Understanding the HW-201 IR Obstacle Sensor: The HW-201 IR Obstacle Sensor is an infrared sensor that detects objects in its range. It works by emitting infrared light and measuring the reflection of that light. If an object is detected, the sensor will output a signal, which can then be used to trigger actions like stopping a robot or, in our case, controlling the movement of a servo motor. The sensor has two main components: The IR LED – It emits infrared light.
