The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe.
Solenoid door lock arduino.
Mifare rc522 rfid kit.
Hall effect sensor will be placed on the door frame and the magnet on the door itself.
Here a hall effect sensor and a magnet are used to detect the door movement.
Single channel 5v relay breakout board.
Controlling solenoids with arduino.
In this tutorial we will look at the basics of solenoids and how they work.
This is the hardware connection and the components needed.
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.
We used analog pins since we need more that 14 digitals pins for this project.
First of all we will make the connection to the 4 4 keypad.
Arduino controlled lock box with solenoid and rfid.
We are going to switch a small 5v solenoid on and off in intervals.
12vdc solenoid door lock.
Then we will design a small circuit that can drive a solenoid from the input output pins on your arduino board.
Watch this video for more info on how to make an rfid solenoid door lock on arduino.
An rfid based door lock with cyclops as display.
Project tutorial by robotgeek projects team.
I became interested in controlling solenoids for robotic music applications.
For connecting the keypad with the arduino we are using both analog and digital pins.
