Arduino & ESP32 Robotics Code Generator

Generate ready-to-upload code for your robots in seconds.

Arduino / ESP32 Code Generator

Choose a template, set your pins, and generate a ready-to-upload .ino sketch.

Motor Driver Pins

Quick notes
  • Arduino Bluetooth RC Car uses Serial at 9600 baud (HC-05/06).
  • ESP32 Bluetooth RC Car uses BluetoothSerial (name: ESP32_Car).
  • Line Follower expects 3 digital sensors (L, M, R) and 4 motor outputs.

What is Arduino & ESP32 Robotics Code Generator

This free online tool helps makers, students, and hobbyists generate Arduino and ESP32 code for their robotics projects without needing to write it from scratch. Whether you’re building a Bluetooth-controlled RC car, a line-following robot, or an ESP32-based smart car, this tool instantly creates clean, ready-to-upload Arduino sketches.

Simply choose your project type, enter your motor and sensor pins, and download a .ino file that you can directly upload to your board. Perfect for beginners, educators, and robotics competitions like Robo Wars, Robo Soccer, or RC Car racing.

🔹 Help & Hardware Guide

🛠️ 1. Arduino Bluetooth RC Car

  • Connections:
    • Connect the 4 motor driver pins to your Arduino digital pins.
    • Connect HC-05 Bluetooth module → RX to Arduino TX, TX to Arduino RX.
    • Power the motor driver with 5V and connect the enable pins to 5V.
    • Make sure to share a common ground between Arduino, motor driver, and power supply.
  • Before Uploading Code:
    • Disconnect the Bluetooth module from RX/TX pins, otherwise the code won’t upload.
    • After uploading, reconnect the Bluetooth module.
  • Use Cases:
    • RC Cars, Robo Soccer, Robo Wars, Remote-controlled bots.

🛠️ 2. Arduino Line Follower Robot

  • Connections:
    • Connect 3 IR sensors to Arduino pins (Left, Middle, Right).
    • Connect the 4 motor driver pins to Arduino.
    • Power the motor driver with 5V and connect enable pins.
  • How It Works:
    • The middle sensor keeps the robot moving straight.
    • Left/right sensors help it correct its path when it deviates.
  • Use Cases:
    • Autonomous navigation, Maze-solving robots, Line racing competitions.

🛠️ 3. ESP32 Bluetooth RC Car

  • Connections:
    • Connect 4 motor driver pins to ESP32 GPIO pins.
    • No external Bluetooth module needed — ESP32 has built-in Bluetooth.
    • Power the motor driver with 5V and connect enable pins.
  • Before Uploading Code:
    • No need to remove anything — just connect ESP32 via USB and upload.
  • Control:
    • Connect your phone to the ESP32 via Bluetooth.
    • Use any Bluetooth terminal app to send commands: F (forward), B (backward), L (left), R (right), S (stop).
  • Use Cases:
    • Advanced RC cars, Smart robots, Mobile-controlled rover projects.
