Solenoid Door Lock Arduino

Digital door lock using arduino circuit diagram.

Solenoid door lock arduino. Project tutorial by robotgeek projects team. Mifare rc522 rfid kit. In this tutorial we will look at the basics of solenoids and how they work. Single channel 5v relay breakout board.

12vdc solenoid door lock. 3 7v 1100mah li ion battery. Then we will design a small circuit that can drive a solenoid from the input output pins on your arduino board. If you are using arduino mega then there is no need to use analog.

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. First of all we will make the connection to the 4 4 keypad. We are going to switch a small 5v solenoid on and off in intervals.

For connecting the keypad with the arduino we are using both analog and digital pins. An rfid based door lock with cyclops as display. Controlling solenoids with arduino. 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.

The cyclops eyes will turn red on wrong rfid tag and green on authorized rfid tag. I became interested in controlling solenoids for robotic music applications. The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe. Arduino controlled lock box with solenoid and rfid.

Watch this video for more info on how to make an rfid solenoid door lock on arduino.
