12vdc solenoid door lock.
Solenoid door lock arduino.
Digital door lock using arduino circuit diagram.
Arduino controlled lock box with solenoid and rfid.
Mifare rc522 rfid kit.
Single channel 5v relay breakout board.
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.
Hall effect sensor will be placed on the door frame and the magnet on the door itself.
Controlling solenoids with arduino.
I became interested in controlling solenoids for robotic music applications.
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.
This is the hardware connection and the components needed.
We are going to switch a small 5v solenoid on and off in intervals.
3 7v 1100mah li ion battery.
For connecting the keypad with the arduino we are using both analog and digital pins.
Project tutorial by robotgeek projects team.
First of all we will make the connection to the 4 4 keypad.
If you are using arduino mega then there is no need to use analog.
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.
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.
