Arduino-based Electronic Lock
thingiverse
This project features a servo-based door lock controlled by an Arduino Nano and powered by a standard SG90 servo. The means to open the lock can be anything, from a simple keypad through magnetic hall sensors to Bluetooth or RFID. This project contains complete materials from my Arduino Workshop SIG I presented at ZodiaCon 2017 (www.zodiacon.org). In addition to STLs, there are several 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: 1. Testing the environment (blinking the LED) 2. Using the OH3144 Hall Sensor 3. Using the 4x4 matrix keyboard 4. Using the SG90 servo 5. Simple lock controlled by magnetic sensor 6. Simple lock controlled by keyboard 7. Finished project - lock with changeable code stored in EEPROM. The following electronic components are required: * Arduino Nano (or any other Arduino, but the holder is designed for Nano) * OH3144 Hall Sensor * SG90 servo * 4x4 matrix keyboard
