Hello everyone,
I'm new to Arduino and I'm trying to use the fingerprint sensor module, the issue is that the sensor isn't showing up when I run the "enroll" program in the sensor library example.
I am using an Arduino WiFi Rev 2
Here is how I have it wired:
Red Wire: 5v
Black Wire: GND
White: pin 3
Green: pin 2
Blue: Not connected
Yellow: Not connected
Does anybody know why this isn't working? I'm hoping it's something simple.
Post the actual code you're using (don't forget the code tags!).
Post the exact output you get (also use code tags!).
You should consider using pin 0 and 1 (Serial1) on the UNO WiFi (remember, despite it's name it's complete different to an UNO).
in particular, 7. If you are posting code or error messages, use "code" tags
This is what happens when you do not
if you have a module that is not working, do not say "A GPS" or "the fingerprint sensor". Show us a link to the particular sensor, and a link to the datasheet if available
you get a strong sense of deja vu in this place
