Smart Parking System

An IoT-based system that detects car entry and exit using sensors and logs the data into Google Sheets. It uses RFID, NodeMCU, and Google Apps Script for real-time monitoring and notifications.

Sample Arduino Code Snippet

// Detect vehicle entry and send UID
if (vehicleDetected()) {
  String uid = readRFID();
  Serial.println("ENTRY:" + uid + ":" + availableSlots + ":" + assignedSlot);
  openGate();
}
