Arduino-based Electronic Lock

This is servo-based door lock controlled by Arduino Nano and powered by standard SG90 servo. The means to open the lock can be anything, from simple keypad trough magnetic hall sensors to Bluetooth or RFID.

This project contains complete material from Arduino Workshop SIG I did at [ZodiaCon 2017](https://www.zodiacon.org).

In addition to STLs, there are the following files available:
* `Slides.pdf` - presentation slides from my talk
* `Handbook-CS.pdf` - lab handbook in Czech language
* `Handbook-EN.pdf` - lab handbook in English language
* `Code.zip` - source code for all labs

The following labs are included:
01. Testing the environment (blinking the LED)
02. Using the OH3144 Hall Sensor
03. Using the 4x4 matrix keyboard
04. Using the SG90 servo
05. Simple lock controlled by magnetic sensor
06. Simple lock controlled by keyboard
07. Finished project - lock with changeable code stored in EEPROM.

The following electronic components are required:
* Arduino Nano (
