DIY RC Car Controlled with Flysky Transmitter (Arduino + L298N Guide)

In this project tutorial, you'll learn how to build a custom Arduino-based RC car that is remotely controlled using the Flysky FS-i6s radio transmitter. We’ll walk you through everything — from transmitter channel setup to motor driver integration — so that you can bring your radio-controlled vehicle to life using widely available electronic components.

Whether you're a beginner or an RC enthusiast, this guide offers a practical learning experience in robotics, embedded systems, and RC communication.

Transmitter Configuration:

• Set AUX Channel 5 → SWB (Switch B)

• Set Channel 6 → SWA (Switch A)

This step ensures that your transmitter toggles can control speed and steering on separate channels for smooth operation.

Components Used:

• L298N Motor Driver

• Arduino Uno

• 12V Battery Pack

• 2× BO Motors

• Flysky FS-i6s Transmitter & Receiver

• Jumper Cables

• Wheels & Chassis

Step-by-Step Instructions:

Step 1: Assemble your chassis and securely mount the BO motors and wheels.
→ N motor driver outputs (OUT1/OUT2 and OUT3/OUT4).

Step 3: Wire the L298N inputs (IN1, IN2, IN3, IN4) to Arduino digital pins (you can choose 6, 7, 8, 9 for example).

Step 4: Power the motor driver with a 12V battery. Connect the GND to Arduino’s GND.

Step 5: Connect the Flysky receiver's signal pins (usually CH1 and CH2) to Arduino analog pins (A0 and A1).

Step 6: In the transmitter, assign Channel 5 to Switch B and Channel 6 to Switch A under the AUX Channel settings menu.

Step 7: Upload the control code using the Arduino IDE. The code reads PWM values from the RX and drives the motors accordingly.
