Solenoid Door Lock Arduino

We used analog pins since we need more that 14 digitals pins for this project.

Solenoid door lock arduino.

If you are using arduino mega then there is no need to use analog. Hall effect sensor will be placed on the door frame and the magnet on the door itself. 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. Watch this video for more info on how to make an rfid solenoid door lock on arduino.

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. In this tutorial we will look at the basics of solenoids and how they work. For connecting the keypad with the arduino we are using both analog and digital pins.

Then we will design a small circuit that can drive a solenoid from the input output pins on your arduino board. Controlling solenoids with arduino. Single channel 5v relay breakout board. We are going to switch a small 5v solenoid on and off in intervals.

The cyclops eyes will turn red on wrong rfid tag and green on authorized rfid tag. An rfid based door lock with cyclops as display. 3 7v 1100mah li ion battery. 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.
