Finger print scanner

Using Arduino Programming Questions
#1

I want to build a lock with a finger print scanner with this scanner Fingerprint Scanner - TTL (GT-521F32) - SEN-14518 - SparkFun Electronics

I download the finger print library from the link shown below

https://github.com/sparkfun/Fingerprint_Scanner-TTL/tree/master/FPS_GT511C3

I am using Arduino mega ADK, and I connect the TX and RX of the sensor to A8 and A9.

However when I tried to upload the blink example I get the following error message

Arduino: 1.6.4 (Mac OS X), Board: "Arduino Mega ADK"

sketch_dec23b.ino:1:25: fatal error: FPS_GT511C3.h: No such file or directory

Although when I check the library folder, I found the file (FPS_GT511C3.h)

Also, the LED of the sensor is not ON

Below is the arduino code

#include "FPS_GT511C3.h"
#include "SoftwareSerial.h"

FPS_GT511C3 fps(A8, A9);

void setup()
{
	Serial.begin(9600);
	fps.UseSerialDebug = true; // so you can see the messages in the serial debug screen
	fps.Open();
}


void loop()
{
	// FPS Blink LED Test
	fps.SetLED(true);
	delay(1000);
	fps.SetLED(false);
	delay(1000);
}/code]


Please I need the help in this matter, thanks

Although when I check the library folder, I found the file (FPS_GT511C3.h)

Which library folder? There is one for user downloaded libraries and one for core libraries.

#include "SoftwareSerial.h"

On the Mega? Why?

Why do you think that you can do SoftwareSerial on pins A8 and A9?

#3

Have you tryed with #include <FPS_GT511C3.h> ? Is the spelling correct (file names are case sensitive)?

Cheers, Ale.

This is the link I used to download the library

Also, I chose A8 and A9 because they support hardware serial.

FutureEngineer:
Also, I chose A8 and A9 because they support hardware software serial.

Fixed that for you. :wink:

#6

This is the link I used to download the library

That does not define what you did with the zip file that was downloaded.

#7

I upzipped the folder and paste it at this location

documents / arduino / libraries.

and when I open arduino program version 1.6.4, the three files for the library were available at file / examples. Now it's taking long time to upload, and it's still not uploaded.

When I tried other version of arduino, it get uploaded but I get different message at the serial port: starting modem test ..." - contents that are not written in the file "

Please help, Thanks.
