Solenoid Door Lock using Arduino and RFID

In this DIY project we use a real Solenoid Door Lock and control it with RFID and Arduino. Here a Hall Effect sensor and a magnet are used to detect the door movement. Hall Effect sensor will be placed on the door frame and the magnet on the door itself. When the Hall Effect sensor and magnet are close to each other, Hall Effect sensor will be in a low state and the door will remain closed, and when the sensor and magnet are not close means the door is open and hall sensor is in the high state.

RFID Interfacing with PIC Microcontroller

To read the Passive RFID cards and tag, we need a microcontroller with UART hardware. If we select a microcontroller without UART, we need to implement software UART. Here we are using PIC Microcontroller PIC16F877A for interfacing RFID. We will simply read the unique identification no. of RFID tags and display it on 16×2 LCD.

Raspberry Pi Based RFID Attendance System

In this RFID based Attendance System project, we will explain you that how can we authorize and count attendance automatically by using RFID cards. RFID Technology (Radio Frequency Identification and Detection) is commonly used in schools, colleges, offices and stations for various purposes to automatically keep track of people.  Here we will count the attendance of an authorized person by using RFID.
