ESP32-C3_-_RFID

Description :

Build a securised system with an ESP32-C3 and a badge reader to valid or unvalid the access

There's 4 use's cases :

The badge is valid and has 3 access per day and the green diod is turn on
The badge is unvalid and the red diod is turn on
The badge is unknow and the yellow diod is turn on
One badge has an unlimited access

When a badge is checked, new logs are created and saved in the Database

Prerequisites

The project uses :

ESP32-C3 (The electronics card that will be connected to the wifi and get the access badge behavior)
Breadboard (to connect all the electronics together)
3 leds (one green, one red, one yellow)
Some cable to connect everything
A resistor based on 220 Ohm Ω
RFID-RC522 (to read the badge)
Arduino Software (to code the ESP32-C3 behavior)
PyCharm (to code with Python 3.11 to interract with the DB)
MongoDB (the database)

Setup

Set the electronics structure

Schema of the electronics structure

Documentation of the connections between the differents electronics

ESP32-C3 GPIO2 -> Green led -> Resistor -> GRND
ESP32-C3 GPIO3 -> Orange led -> Resistor -> GRND
ESP32-C3 GPIO4 -> Red led -> Resistor -> GRND
ESP32-C3 GPIO6 -> RFID-RC522 SDA
ESP32-C3 GPIO7 -> RFID-RC522 RST
ESP32-C3 GRND -> RFID-RC522 GRND
ESP32-C3 3V3 -> RFID-RC522 3V3
ESP32-C3 GPIO10 -> RFID-RC522 MOSI
ESP32-C3 GPIO9-> RFID-RC522 MISO
ESP32-C3 GPIO8-> RFID-RC522 SCK

Set the Arduino program that will turn on/off the leds

Set the MongoDB

##### Step 1
Download MongoDB (Compass) -> https://www.mongodb.com/try/download/compass

##### Step 2
Set Database and configure Network Access 

##### Step 3
Get the connexion link to use Database in Python

Set the Python code

##### Step 1
Download Python (3.12.X)

##### Step 2
import mongodb (pymongo)

##### Step 3
Set the MongoDB (Client) -> client = MongoClient('mongodb+srv://USER:<PASSWORD>@SERVER.mongodb.net/')

##### Step 4
Get database -> db = client['DATABASE']

##### Step 5 
Create socket and connect it to the arduino
