MQTT based RFID Door Lock Using Ardunino Cloud

Showcasing my IOT project which used Ardunio Cloud and MQTT communication standard to log and control the access management of a RFID based door lock.

Arduino IoT Cloud Variables

String entryID;

String whiteList;

PINOUT (NodeMCU 8266 ESP-12E)

MOSI: GPIO 13 - D7

MISO: GPIO 12 - D6

SCK/ CLK: GPIO 14 - D5 (Slave Clock or Clock)

SS/ CS/ SDA : GPIO 15 - D8 (Chip select or Slave Select)

RST : GPIO 2 - D4

Example whiteList input ->

"00_00_00_00-Jai Vaswani;00_01_02_03-Sumir Broota"

1) First, split based on ';'
2) For each part of string after splitting, split based on '-'
3) First part of this gets added to decimal_array
4) Second part of this gets added to names_array
