✨ What Makes This Tool Different?
Forget static, confusing diagrams. This interactive tool lets you visualize the internal logic of the L293D:
Click Any Pin → Instantly see if it’s an Enable, Input, Output, or Power pin.
Visualize the H-Bridge → See how internal Darlington pairs route current to your motors.
Dual-Supply Breakdown → Clearly distinguish between $V_{CC1}$ (Logic) and $V_{CC2}$ (Motor Power).
Logic Truth Table → Click inputs to see how the outputs will react in real-time.

🔧 Key Features You Can Explore:
| Feature | What You'll Learn
Dual H-Bridge | How to control two DC motors or one stepper motor independently.
Internal Clamp Diodes | How the L293D protects your circuit from inductive back-EMF.
Enable Pins (1,2EN & 3,4EN) | How to use PWM for speed control and braking.
| Power Separation | Why keeping 5V logic and 12V+ motor power separate is critical.
Each pin click reveals:
✅ Voltage & Current Limits (600mA per channel / 1.2A peak)
✅ Internal Logic Path (How signal flows from Input to Output)
✅ Wiring Diagrams (Common Arduino/ESP32/ATtiny connections)
✅ Heat Dissipation Tips (Identifying the Ground/Heat-sink pins)📌 How to

Use This for Your Projects:
Speed Control PlanningClick the Enable pins to see how to apply PWM for variable motor speed.Directional LogicToggle the Input pins (IN1, IN2) in the explorer to see which way the motor spins (CW/CCW/Brake).Power ManagementIdentify Pin 8 (V_CC2) and Pin 16 (V_CC1) to ensure you don't fry your microcontroller.TroubleshootingMotor not turning? Click the pins to verify your high/low logic levels and common ground points.🚀 Perfect For:| Role | Use Case || :--- | :--- || Beginners | Understand H-Bridge logic without burning out chips. || Robotics Makers | Rapidly wire up 2WD or 4WD robot chassis. || Educators | A visual aid for teaching motor induction and logic gates. || Engineers | Quick reference for thermal limits and pin-out configurations. |
