Access control module based on Arduino Nano, require hardware support (RFID reader and servo)

The entire system is composed of three core modules, which are solar power module, access control module and LCD display module. Detailed use of every key component of the early prototype is demonstrated below.

Solar panel: provide auxiliary power supply directly to the power banks
Pressure regulator: regulate voltage

RFID reader: read information in an ID card
Servo: rotate and make the doors open
Magnet switch: control the status of door lock

LCD1602 screen: deliver text
Clock module: used for chronograph

The actual connection follows the hand sketch.
