RFID Smart Autonomous Car

This project is an autonomous smart car system based on an ESP32 and Arduino GIGA.
The ESP32 handles RFID/NFC card detection, WiFi UDP communication, LED effects, and command forwarding.
The Arduino GIGA controls the vehicle movement using Hall sensors, servos, and stepper motors.

Features

• RFID/NFC card control using RC522
• WiFi UDP communication between devices
• NeoPixel LED animation and light control
• Front and rear servo steering
• Dual stepper motor drive system
• Hall sensor based steering correction
• Sensor enable/disable commands from RFID cards
• Stop and resume vehicle logic
• Straight driving mode when sensors are disabled

Hardware Used

• ESP32
• Arduino GIGA
• RC522 RFID/NFC reader
• NeoPixel LED strip
• 2 Hall sensors
• 2 Servo motors
• 2 Stepper motors with drivers
• WiFi network for UDP communication

System Overview

The ESP32 reads RFID cards and sends commands either through UDP or UART.

RFID cards can:

• Open or close doors
• Turn lights on
• Stop or resume the car
• Enable or disable left/right Hall sensors
• Force the car to drive straight

The Arduino GIGA receives sensor commands from the ESP32 over UART and controls:

• Steering servos
• Stepper motor speed
• Hall sensor correction logic

Main Commands

Commands sent from ESP32 to Arduino GIGA:

sensor left on
sensor right on
sensor both on
sensor both off
