i am working with my summer project and i am using R305 fingerprint module with arduino and currently i am facing problem while interfacing r305 fingerprint module with arduino mega
i inserted the RX and TX pins of the r305 on the 10, 11 pins of the mega as mentioned in the adafruit forums and i have also mentioned the pins 10,11 instead of 2,3 in the enrollment code of the installed adafruit library but whenever i upload my program the serial monitor displays " did not find fingerprint sensor ". maybe mega 2560 doesnt detects the fingerprint sensor. i doubt whether this module is compatible with the board or not
i wish if you could just help me with the interfacing
johnwasser: Serial - Arduino Reference "The Arduino Mega has three additional serial ports:
Serial1 on pins 19 (RX) and 18 (TX),
Serial2 on pins 17 (RX) and 16 (TX),
Serial3 on pins 15 (RX) and 14 (TX). "
With all those spare serial ports on the MEGA it is unnecessary to use SoftwareSerial which can conflict with other libraries.
how to disable software serial since the library i used, also use that softwareserial library?
here is the error message when i disable #include softwareserial.h in my sketch :
In file included from Fingerprint_with_php110415.ino:40:0:

I m still facing same problem in my r305 while interfacing to mega2560. I changed my serial pin 2,3 to10,11 .serial monitor is still displaying " fingerprint sensor didnt found". Some places, they suggested to use sfg demo fingerprint scanner software to interface but i didnt get any download link of it ..
Kindly help me
I am facing the same problem on interfacing the R 305 with arduino uno,It shows that "Did not find fingerprint sensor :(".I am using the adafruit library also it shows one more error that "WARNING: Spurious .github folder in 'Adafruit Fingerprint Sensor Library' library" on uploading the code to the board.
I am facing the same problem on interfacing the R305 with arduino uno it responds on the serial monitor as "Did not find fingerprint sensor :(".Also it shows one more error on uploading the code(i am using adafruit library) as"WARNING: Spurious .github folder in 'Adafruit Fingerprint Sensor Library' library".
