I became interested in controlling solenoids for robotic music applications.
Solenoid door lock arduino.
This is the hardware connection and the components needed.
Hall effect sensor will be placed on the door frame and the magnet on the door itself.
Controlling solenoids with arduino.
In this tutorial we will look at the basics of solenoids and how they work.
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.
The cyclops eyes will turn red on wrong rfid tag and green on authorized rfid tag.
The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe.
12vdc solenoid door lock.
We used analog pins since we need more that 14 digitals pins for this project.
Project tutorial by robotgeek projects team.
Mifare rc522 rfid kit.
An rfid based door lock with cyclops as display.
Watch this video for more info on how to make an rfid solenoid door lock on arduino.
3 7v 1100mah li ion battery.
If you are using arduino mega then there is no need to use analog.
Digital door lock using arduino circuit diagram.
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.
Arduino controlled lock box with solenoid and rfid.
We are going to switch a small 5v solenoid on and off in intervals.
Here a hall effect sensor and a magnet are used to detect the door movement.
