Скачать или смотреть Arduino uno Rfid lock system with changeable password

To create an Arduino Uno RFID lock system with a changeable password, you will need the following components:

1. Arduino Uno board
2. RFID module (e.g., RC522)
3. Servo motor
4. Keypad module
5. Jumper wires
6. Breadboard
7. Solenoid lock or any locking mechanism

Here's a step-by-step guide to creating the RFID lock system:

Connect the RFID module:
Connect the VCC pin of the RFID module to the 3.3V pin on the Arduino Uno.
Connect the GND pin of the RFID module to the GND pin on the Arduino Uno.
Connect the RST pin of the RFID module to digital pin 9 on the Arduino Uno.
Connect the IRQ pin of the RFID module (if available) to any digital pin on the Arduino Uno.
Connect the MISO, MOSI, and SCK pins of the RFID module to the corresponding pins on the Arduino Uno (SPI communication).
Connect the SDA pin of the RFID module to digital pin 10 on the Arduino Uno.
Connect the servo motor:
Connect the VCC pin of the servo motor to the 5V pin on the Arduino Uno.
Connect the GND pin of the servo motor to the GND pin on the Arduino Uno.
Connect the signal pin of the servo motor to digital pin 3 on the Arduino Uno.
Connect the keypad module:
Connect the VCC pin of the keypad module to the 5V pin on the Arduino Uno.
Connect the GND pin of the keypad module to the GND pin on the Arduino Uno.
Connect the row pins of the keypad module to digital pins 4, 5, 6, and 7 on the Arduino Uno.
Connect the column pins of the keypad module to digital pins 8, 9, 10, and 11 on the Arduino

Remember to always consider security measures and encryption techniques when dealing with sensitive information like passwords.
