Fingerprint Sensor not found with Arduino

Post by PFain »

I've recently been trying without success to incorporate the fingerprint sensor into a lockbox project.
  • I've been using an Arduino Uno that has been verified with other projects/sketches
    The AdaFruit_Fingerprint libraries have been installed and show up in the Example sketches
    The sensor does flash red initially when it receives power
    I have checked continuity on the 4 wires to the board
    I have confirmed that it is receiving 5V from the Uno
When I run the enroll or fingerprint sketches however the serial monitor will display
"fingertest fingerprint sensor not found :("

It seems like a dud sensor after my troubleshooting. Anything else I should try before requesting a replacement?

Please post photos showing your wiring to the sensor.
Have you tried enrolling with the SFGDemo software? https://learn.adafruit.com/adafruit-opt ... th-windows
