DIY RFID DOOR LOCK System

Hii friends Today I'll Show You How To Make RFID Door Lock System Using Arduino Nano

The arduino based RFID door lock system is secure and responsive as compared to other systems. With the use of arduino, it becomes much easy to design. Program a code and upload it to arduino just like a plug and play device. It is simple and cost efficient project and can be used as a basic access control mechanism. Their main advantage is contactless communication and RFID tags can work in any environmental conditions.

Supplies:

You'll nees Some Componenets

• Plastic Box
• Rfid Module
• 12V solenoid Lock
• Arduino nano
• 1ch Relay Module
• Some Jumper Wire
• 5V TO 12v CONVERTOR
• DC Socket
• 5V adapter

Step 1: Solder RFID Module

Solder the mail header with Rafid

Step 2: Stick RFID in the Lid

Step 3: Connections

Combine all the components with the arduino as shown in the Pic

ARDUINO to RFID reader

pin 11 to MISO

pin 12 to MOSI

pin 13 to SCK

pin 10 to NSS

pin 9 to RST

These were the connection from Arduino to RFID reader

Relay Module Arduino Nano

Step 6: 5V Power Supply

Step 7: Complete

Step 10: Nextpcb

As per my circuit diagram, I have made a PCB layout and order it on NEXTPCBI have received this PCB after 7 days, the PCB quality is very good and also the price of PCB is also low

if you don't make your PCBs yourself, where do you make them?Personally, I do not have the space and the courage (nor the skill) to do them my self.For SF, I turn to Util-Pocket, because I find that the quality is excellent for the price. For the DF (with metallic holes), I tried several companies, all of which do a good job, but it costs a lot.This time I addressed myself here. I had 3 circuits to do, totaling an average surface of 49 cm2.When I saw that the minimum quantity to order was 5 PCBs, I continued my order out of curiosity, just to see the quote. And when I saw the asking price, I placed the order. Nextpcb
