Solenoid Door Lock Arduino

The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe.

Solenoid door lock arduino. If you are using arduino mega then there is no need to use analog. 3 7v 1100mah li ion battery. 12vdc solenoid door lock. This is the hardware connection and the components needed.

Arduino controlled lock box with solenoid and rfid. 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. Controlling solenoids with arduino.

We are going to switch a small 5v solenoid on and off in intervals. Hall effect sensor will be placed on the door frame and the magnet on the door itself. Then we will design a small circuit that can drive a solenoid from the input output pins on your arduino board. We used analog pins since we need more that 14 digitals pins for this project.

Mifare rc522 rfid kit. Here a hall effect sensor and a magnet are used to detect the door movement. First of all we will make the connection to the 4 4 keypad. 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. 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. 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. Single channel 5v relay breakout board.
