Build a Remote Controlled Car with Camera

Components Required

• Microcontroller: ESP32
• Camera Module: ESP32-CAM
• Chassis: RC car chassis
• Motors: DC motors or stepper motors with motor driver (L298N)
• Power Supply: Rechargeable battery pack (LiPo or NiMH)
• Wi-Fi Module: Integrated in ESP32
• Remote Control Interface: Smartphone or PC with web browser
• Jumper Wires and Breadboard

Overview

This project involves using an ESP32 microcontroller equipped with a camera to create a remote-controlled car. The camera allows for live streaming video, enabling you to see from the car's perspective while controlling it remotely.

Steps to Implement

1. Assemble the Chassis

   Mount the motors and wheels on the chassis, attach the motor driver, and connect the motors to the driver.

2. Connect the ESP32-CAM

   Connect the ESP32-CAM to the motor driver and ensure proper wiring for GPIO pins.

3. Wiring Connections

   Make connections to the motor driver and power supply. Ensure the ESP32 is powered appropriately.

4. Install the Arduino IDE

   Download and install the Arduino IDE, adding the ESP32 board support and necessary libraries.

5. Upload Code

   Use the provided Arduino sketch to control the car and stream video.

   
   #include "esp_camera.h"
   #include 
   
   #define IN1 12
   #define IN2 14
   #define IN3 27
   #define IN4 26
   
   const char* ssid = "YOUR_SSID";
   const char* password = "YOUR_PASSWORD";
   
   void setup() {
       // Setup code...
   }
   
   void loop() {
       // Control logic...
   }
                       

6. Implement Web Interface

   Create a simple web server on the ESP32 to control the car and view video.

7. Testing

   Connect your device to the same Wi-Fi and access the web interface to control the car.
