Solenoid Door Lock Arduino

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.

Solenoid door lock arduino.

The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe. Hall effect sensor will be placed on the door frame and the magnet on the door itself. Digital door lock using arduino circuit diagram. For connecting the keypad with the arduino we are using both analog and digital pins.

Controlling solenoids with arduino. 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. First of all we will make the connection to the 4 4 keypad.

Project tutorial by robotgeek projects team. The cyclops eyes will turn red on wrong rfid tag and green on authorized rfid tag. Arduino controlled lock box with solenoid and rfid. 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. We used analog pins since we need more that 14 digitals pins for this project. Mifare rc522 rfid kit. This is the hardware connection and the components needed.

An rfid based door lock with cyclops as display. I became interested in controlling solenoids for robotic music applications. If you are using arduino mega then there is no need to use analog. 3 7v 1100mah li ion battery.

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.
