Motor and servo drive control with Arduino

This project is a control system for two DC motors and one servo drive using an Arduino Uno microcontroller. It was implemented for educational purposes to demonstrate skills working with the L293D motor driver, potentiometer, servo drive, and breadboard.

Project goal:
Create a controllable platform where the user can change the position of the servo motor or adjust the direction and speed of the DC motors using a potentiometer.

Components used:

Arduino Uno board

L293D motor driver

2 DC motors

1 servo drive

Potentiometer

Breadboard

Power supplies (USB and 9V battery)

Functionality:

Control the rotation direction of two motors via the L293D driver.

Monitor the position of the servo motor using a potentiometer.

Use the analog signal from the potentiometer to set speed or angle.

Separate power supply for motors and controller, ensuring stable system operation.

Skills demonstrated in the project:

Circuit design on a breadboard

Working with external power and controller protection

PWM signal control

Using a potentiometer for analog input

Programming Arduino to operate motors and sensors

Applications:
Such a system can be used to create:

Robotic carts

Manipulators

Interactive models and simulators
