Re: Arduino Fingerprint scanner project
Finally starting to try and do the fingerprint scanner project but currently running into a few problems. One problem is when I hook up the fingerprint scanner directly into the Arduino board the red light of the scanner comes on for only a fraction of a second. i have the Red wire-5V pin, Black wire- Gnd, White wire- Pin 3 and Green wire to Pin 2.
The second problem have encountred is loading the correct library i guess. The libary i loaded was the Adafruit_fingerprint.cpp but when i try and upload it to my Arduino Uno board i recieve this error:
core.a(main.cpp.o): In function `main':
