access_control

Microcontroller project with the ESP8266 and MF RC522 RFID card reader to control the locking and unlocking of a door.

Hardware used:

• ESP8266 (NodeMCU v2.0)
• Mifare RC522 RFID card reader from Banggood
• MG995 High Torgue Analog Servo from Banggood
• WS2812 RGB LED

Wiring:

Wiring the MF RC522 to ESP8266 (ESP-12) or NodeMCU v2

RST = GPIO5 (D1) SDA(SS) = GPIO4 (D2) MOSI = GPIO13 (D7) MISO = GPIO12 (D6) SCK = GPIO14 (D5) GND = GND 3.3V = 3.3V
