Mastering Arduino Servo Control: A Comprehensive Tutorial

Introduction

Hello enthusiasts, welcome back to our latest post featuring Arduino UNO. In this article, we’ll demonstrate how to create your own Arduino servo control remote system. This setup involves utilizing an IR remote control for wireless signal transmission, coupled with a TSOP IR receiver module on the receiving end. To control the servo motor, a simple button press on the IR remote suffices. Explore additional articles on IoT and basic electronics. Ensure accurate connections and upload the code as instructed.

Description

Initially, the servo motor is positioned at 0 degrees.
When you press buttons on the IR remote, the Arduino servo control initiates positional changes.
The code already specifies various positions and their corresponding codes, allowing customization as needed.
For instance, pressing button 1 on the IR remote triggers rotation of the servo motor to a specific position.
This circuit is the simplest setup for this project. Now, LEDs are integrated with the Arduino, enabling them to automatically illuminate upon pressing the IR remote buttons.
The inclusion of LEDs in the circuit serves the purpose of indicating signal reception by the Arduino.
In the third circuit iteration, an LCD module is incorporated, providing visibility into the values received by the Arduino.
Feel free to explore our Arduino IR remote control project for reference.

About the Code

Initially, we define the data type for each variable and subsequently assign their respective values. Following this, we specify the pin modes for every input or output pin utilized in the setup. Within the loop function, we acquire user input to facilitate ongoing processes. To execute specific operations, we utilize if conditional statements, ensuring execution only if the foundational condition proves true.
