IoT Lab Experiment 4 | DC Motor Control using Arduino | VTU 7th Sem BCS701 | Motor Driver Interface

Описание: In this video, we perform IoT Lab Experiment 4 (BCS701) for VTU 7th Semester – 22 Scheme, where we control a DC motor using the Arduino board.

🔹 Objective:
To interface a DC motor with Arduino and control its ON/OFF state and rotation using a motor driver or transistor circuit.

🔹 Concepts Covered:

Working of DC motors

Using NPN transistor or L293D/L298N motor driver IC

Flyback diode concept for motor protection

Motor speed control using PWM (optional)

Direction control using motor driver

IoT applications in automation and robotics

🔹 Components Required:

Arduino UNO

DC Motor

L293D / L298N Motor Driver OR NPN transistor

Flyback diode

External power supply (if needed)

Jumper wires & breadboard

This experiment builds the foundation for IoT-based automation systems, such as robotic control, smart appliances, and home automation motors.
