Arduino code for Relay and R503 fingerprint sensor

Post by dsafranyik »

Hi,

Could you please help me with a code where I can control a relay with R503 fingerprint sensor? I want to connect a solenoid lock to the relay.

Thank you!

You have to take input from the fingerprint sensor. You'll have to switch the relay with the Arduino. Here are two tutorials. You have to cascade these two.

Here is also an Arduino UNO Pinout configuration guide that you may find helpful.
