Hi! I have a college project for which I have to interface a fingerprint module and a lcd display with an arduino uno. When I connect the LCD display, the fingerprint module and the arduino together the fingerprint module does not work. Any suggestions on what I can do to resolve the issue?
You could always post your code and links to the fingerprint reader. And the display if it's not the usual 1602 type? Oh, and how you've got it all connected perhaps?
