RFID-Based Car Parking System Using Arduino RFID-Based Car Parking System Using Arduino This project involves designing an RFID-based car parking system using Arduino UNO , RFID module , IR sensors , 16x2 LCD with I2C , MG90S servo motor , and other essential components. The system automates the entry and exit process for vehicles using RFID authentication. How the System Works When a vehicle reaches the entrance, IR Sensor 1 is triggered. The LCD display prompts the driver to scan an RFID card . If the scanned card is registered , the servo motor opens the gate , allowing entry. If the card is not registered , the LCD will display "Access Denied" and the gate remains closed. After the vehicle passes through IR Sensor 2 , the gate automatically closes after 2 seconds . The system manages four parking slots , but this can be...

Drill + Cutting Machine Using 775 DC Motor and PVC Pipe This project involves designing a DIY drill and cutting machine using a 775 DC motor , 2-inch PVC pipe with end caps , and essential electrical components. This compact and versatile tool can be used for both drilling and cutting operations, making it a great addition to any DIY workspace. How the System Works The system utilizes a 775 DC motor mounted inside a 2-inch PVC pipe , with a drill chuck attached to the motor shaft. A small switch and push button control the motor’s operation. Power is supplied using a 24V power source , and interchangeable tool heads allow switching between drilling and cutting functions. Components List 775 DC Motor (High torque, 12V-24V) 2-inch PVC Pipe (Body structure) PVC End Caps (Securing motor inside pipe) Chuck (To hold drill bits and saw blade) Drill Bits (For drilling operations) Cutting Saw Blade (For cutting applications) Small Switch (ON/OFF control) Push Button (Momentary opera...
