The cyclops eyes will turn red on wrong rfid tag and green on authorized rfid tag.
Solenoid door lock arduino.
If you are using arduino mega then there is no need to use analog.
An rfid based door lock with cyclops as display.
Hall effect sensor will be placed on the door frame and the magnet on the door itself.
This is the hardware connection and the components needed.
Single channel 5v relay breakout board.
Digital door lock using arduino circuit diagram.
12vdc solenoid door lock.
3 7v 1100mah li ion battery.
For connecting the keypad with the arduino we are using both analog and digital pins.
We used analog pins since we need more that 14 digitals pins for this project.
Here a hall effect sensor and a magnet are used to detect the door movement.
Then we will design a small circuit that can drive a solenoid from the input output pins on your arduino board.
Mifare rc522 rfid kit.
The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe.
Arduino controlled lock box with solenoid and rfid.
We are going to switch a small 5v solenoid on and off in intervals.
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.
I became interested in controlling solenoids for robotic music applications.
Project tutorial by robotgeek projects team.
First of all we will make the connection to the 4 4 keypad.
