Controlling solenoids with arduino.
Solenoid door lock arduino.
Digital door lock using arduino circuit diagram.
Mifare rc522 rfid kit.
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 this tutorial we will look at the basics of solenoids and how they work.
We are going to switch a small 5v solenoid on and off in intervals.
This is the hardware connection and the components needed.
Project tutorial by robotgeek projects team.
An rfid based door lock with cyclops as display.
The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe.
First of all we will make the connection to the 4 4 keypad.
For connecting the keypad with the arduino we are using both analog and digital pins.
12vdc solenoid door lock.
Arduino controlled lock box with solenoid and rfid.
Here a hall effect sensor and a magnet are used to detect the door movement.
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.
If you are using arduino mega then there is no need to use analog.
Then we will design a small circuit that can drive a solenoid from the input output pins on your arduino board.
Single channel 5v relay breakout board.
We used analog pins since we need more that 14 digitals pins for this project.
Hall effect sensor will be placed on the door frame and the magnet on the door itself.
The cyclops eyes will turn red on wrong rfid tag and green on authorized rfid tag.
