    Hi. I'm using the FPS GT511C3and arduino Uno to make an attendance biometric system. I'm using 10k Ohm resistors to create a voltage divider circuit to reduce 5V to 3.3V.

    I followed the exact same procedure to connect hardware that was mentioned in the site in your article. After connecting the FPS to Arduino Uno, I noticed that even though the processor behind is getting heated up the FPS green power LED is not turning on. Can you please help me out?

    Thanking you in advance
