How to Make an IR Remote Controlled Car Using Arduino and L298N Motor Driver
Building a WiFi-controlled car using the NodeMCU ESP8266 and the L298N motor driver is a fantastic project to explore the world of IoT and robotics 🤖. With just a few components and a bit of coding 💻, you can create a simple yet powerful car controlled via your smartphone or computer 📱. Let’s dive into the details!
📝 Circuit Diagram
Connect the components as follows:
IR Receiver (e.g., TSOP1738):
| IR Receiver Pin | Arduino Uno Pin |
|---|---|
| OUT (Signal) | D11 |
| VCC | 5V |
| GND | GND |
L298N Motor Driver:
| L298N Pin | Arduino Pin |
|---|---|
| IN1 | D5 |
| IN2 | D6 |
| IN3 | D9 |
| IN4 | D10 |
| ENA | 5V |
| ENB | 5V |
| VCC | Battery + |
| GND | GND |
| 5V EN | Jumper Cap |
Tip: Connect your DC motors to OUT1 & OUT2, and OUT3 & OUT4.
💻 Code for WiFi Controlled Car
🧪 Test and Troubleshoot
🔋 Use fresh batteries for consistent motor performance.
🔄 Double-check all wires and pin numbers.
📡 Point the remote directly at the receiver and press slowly.
🧰 Use a multimeter to verify motor driver connections.
🎉 Final Thoughts
You’ve now built your own IR-controlled Arduino car — a mini robot that responds to your remote like a charm. It’s an excellent foundation for learning robotics, automation, and Arduino programming.
