Project Description:
********************

In today’s episode, I am going to use R557 3.3V Capacitive Fingerprint Module with Arduino to control an Electronic Door Lock.

So, for this project, you will need an Arduino Uno or Arduino Nano, the R557 Capacitive Fingerprint Module, a 12V Electronic Door Lock, and a relay module.

Since this is a getting-started tutorial, so I am going to cover
1. The R557 Fingerprint Module Technical specifications
2. Its wiring details
3. It’s circuit diagram
4. How to enroll and manage new fingerprints?
5. Arduino Programming and
6. Practical testing.

So, without any further delay, let’s get started!!!
