In this video I explain:
1. components needed / used
2. the wiring / pinouts / connections made
3. helpful security tips
4. a brief explanation of the functionality and code
5. how to obtain your UID
6. additional technologies to consider / use
7. troubleshooting pointers
The script or code for the Arduino Nano (or any other device, just change minor necessary info) that connects an RFID (MFRC522 module) with a 4-pin I2C OLED display module featured in this video can be downloaded from my GitHub link below.
Github link to download the script for Arduino Nano: github.com/rhi...
This code allows you to:
-scan RFID card or fobs
-present UID, PICC type, and messages to the Serial Monitor
-present UID and messages to the connected OLED display
-validate a single user's UID / RFID to present an "UNLOCKED" message on an OLED display
I hope this video helps you all!
