Solenoid Door Lock Arduino

Digital door lock using arduino circuit diagram.

Solenoid door lock arduino.

We used analog pins since we need more that 14 digitals pins for this project. The cyclops eyes will turn red on wrong rfid tag and green on authorized rfid tag. 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. For connecting the keypad with the arduino we are using both analog and digital pins.

First of all we will make the connection to the 4 4 keypad. 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. I became interested in controlling solenoids for robotic music applications. Then we will design a small circuit that can drive a solenoid from the input output pins on your arduino 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. The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe. 12vdc solenoid door lock.

Mifare rc522 rfid kit. Single channel 5v relay breakout board. If you are using arduino mega then there is no need to use analog. We are going to switch a small 5v solenoid on and off in intervals.
