Solenoid Door Lock Arduino

Digital door lock using arduino circuit diagram.

Solenoid door lock arduino.

Mifare rc522 rfid kit. In our previous posts we have built a simple rfid door lock this time we use a real solenoid door lock and control it with rfid and arduino. Controlling solenoids with arduino. Hall effect sensor will be placed on the door frame and the magnet on the door itself.

This is the hardware connection and the components needed. For connecting the keypad with the arduino we are using both analog and digital pins. We used analog pins since we need more that 14 digitals pins for this project. I became interested in controlling solenoids for robotic music applications.

An rfid based door lock with cyclops as display. 12vdc solenoid door lock. The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe. Project tutorial by robotgeek projects team.

Single channel 5v relay breakout board. In this tutorial we will look at the basics of solenoids and how they work. Here a hall effect sensor and a magnet are used to detect the door movement. Then we will design a small circuit that can drive a solenoid from the input output pins on your arduino board.

3 7v 1100mah li ion battery. Watch this video for more info on how to make an rfid solenoid door lock on arduino. We are going to switch a small 5v solenoid on and off in intervals. In this instructable we will be building a simple circuit that will allow us to control a solenoid using the popular physical computing platform arduino.

First of all we will make the connection to the 4 4 keypad.
