# RC Car Control System

A comprehensive remote-controlled car system with live camera feed and gripper control.

## Components

- Arduino MEGA 2560 R3 (Main Controller)

- OV7670 VGA CMOS Camera

- Seeed Studio XIAO ESP32S3

- MG995 Servo (Gripper Base)

- SG5050 Servo (Gripper Claw)

- L298N Motor Driver Modules (x2)

- DC Motors (x4)

## Features

- Real-time video streaming

- Web-based control interface

- Keyboard controls

- Motor control for movement

- Servo-controlled gripper system

- WiFi connectivity

- Mobile-responsive UI

## Setup Instructions

1. **Hardware Setup**

   - Follow the connection diagram in `CONNECTIONS.md`

   - Double-check all power connections

   - Ensure proper grounding

2. **Software Requirements**

   - Arduino IDE

   - Required Libraries:

     - `Servo.h`

     - `Wire.h`

     - `WiFi.h`

     - `WebServer.h`

     - `DNSServer.h`

     - `ESPmDNS.h`

3. **Installation**

   - Upload `arduino_mega.ino` to Arduino MEGA

   - Upload `esp32.ino` to ESP32S3

   - Power up the system

4. **Accessing the Control Interface**

   - Connect to WiFi network "RC_Car" (password: 12345678)

   - Open browser and navigate to http://rccar.local

   - If DNS resolution fails, use the IP address shown on ESP32's serial monitor

## Controls

### Web Interface

- Arrow buttons for movement

- Dedicated gripper controls

- Live camera feed display

### Keyboard Controls

- Arrow keys: Movement control

- Spacebar: Stop

- 'G': Close gripper

- 'O': Open gripper

- 'U': Move base up

- 'D': Move base down

- 'N': Neutral position

## Troubleshooting

1. **No Video Feed**

   - Check camera connections

   - Verify power supply

   - Refresh browser page

2. **Motors Not Responding**

   - Check L298N connections

   - Verify motor power supply

   - Check serial communication between ESP32 and Arduino

3. **Gripper Issues**

   - Verify servo power supply

   - Check servo signal connections

   - Ensure servos are properly calibrated

## Safety Notes

- Always operate on a stable power supply

- Keep the system away from water

- Monitor motor temperature

- Don't exceed servo limits
