🔧 DC Motor Speed Control Explained | Beginner-Friendly TinkerCAD Simulation

In this hands-on tutorial, we explore how to control the speed of a DC motor using basic components like a BJT transistor, photoresistor (LDR), resistor, diode, and eventually PWM with Arduino.

We build the circuit step-by-step in TinkerCAD, adding layers of complexity and understanding how each component contributes to motor control.

🔍 What you'll learn in this video:
How to control DC motor speed using BJT transistor as a switch/amplifier
Using photoresistor (LDR) to make a light-based control system
Importance of flyback diodes in motor protection
Basics of biasing a BJT
Introduction to Pulse Width Modulation (PWM) using Arduino UNO

Preview of using a motor driver IC for more efficient control (covered in next video)

🎓 Ideal for:
Engineering students
Robotics and electronics beginners
Hobbyists using Arduino or TinkerCAD
Anyone preparing for BME, EC, EE, or IN GATE exams

🧪 Tools Used:
✅ TinkerCAD (Free online electronics simulator)
✅ Arduino UNO
✅ DC motor, BJT (NPN), resistors, diode, photoresistor (LDR)

📺 Stay tuned for Part 2 – where we implement PWM with a motor driver module (e.g., L298N) for better efficiency and control.
