Project Overview

A dual-servo control system using Arduino that allows precise control of two servo motors through analog inputs and includes LED feedback.

Completed: 2024
Status: Completed
Type: Robotics Project

Project Description

This project implements a dual-servo control system using Arduino. It uses analog inputs from potentiometers to control the position of two servo motors independently. The system includes an LED indicator that provides visual feedback based on the vertical servo position.

Technical Implementation

The project uses the following components and technologies:

  • Arduino Uno board
  • Two servo motors
  • Two potentiometers for analog control
  • LED indicator
  • Arduino Servo library
