This should be something like an access control system for a locker using a QR code and ESP32. (You will need to create only the schematic, for example in EasyEDA)
Develop an electrical schematic diagram of the device, which:
1. reads the user's QR code
2. checks access via a request to a web server
3. opens the lock upon a positive response
4. informs the user through LEDs.
Main components:
1. ESP32 — microcontroller with Wi-Fi support
2. QR code scanner module — either built-in camera or external scanner UART/USB
3. Electromechanical lock or servo drive — physical opening mechanism
4. Relay (5V) — for switching the lock
5. Indication — two-color LED (green — access granted, red — denied)
6. 5V power supply
Principle of operation
1. The user scans the QR code placed on the website after confirming the agreement
2. ESP32 processes the scanned code and forms an HTTP request to the server, which checks the status of the agreement
3. If the status of the agreement is "completed" (confirmed by both parties), ESP32 sends a signal to the relay
4. The relay closes the power circuit of the lock, opening the locker door
5. After the timer (~5 seconds) ends, power supply is cut off — the locker closes again
6. The LED changes color according to the request result: green — success, red — failure
I ran it through GPT, the main framework looks approximately like this: 
This should be an electrical schematic diagram for the project, which should look like this (typical screenshot):
What to do:
1. Electrical schematic diagram (anywhere, as long as I can open it properly, it can be software like EasyEDA, KiCad, Altium, Fritzing)
2. Description of all components
