hello
i am from bangladesh , i recently purchased a fingerprint device id 751, i ve followed the video tutorial and plugged everything accordingly.i am using an arduino mega 2560 and after connecting it all i am getting is a single red blink and after uploading the code it shows "didnot find the fingerprint sensor"
i have soldered the wires with a header pin ,modified the code in following manner
#if ARDUINO >= 100
SoftwareSerial mySerial(10, 11);
#else
NewSoftSerial mySerial(10, 11);
#endif
still it is not working , and this is simply sad
any wise ideas why this is happening?

Re: fingerprint device 751
Most difficulties with this sensor can be traced to connection problems. Please post a photo showing all your soldering and connections.

Re: fingerprint device 751
Have you tried connecting directly via the SFG program?
Also, try making your connections direct to the Arduino headers. The breadboard is not required and only adds more opportunities for connection problems.

Re: fingerprint device 751
Did you try changing the baud-rate? Some of these ship with different baud-rates. It is usually one of the higher rates, but I would try: 19200, 28800, 38400, 57600, or 115200. http://arduino.cc/en/Serial/begin

Re: fingerprint device 751
that would be helpful,and could you please recheck the product before shipping this time ,
i have another query ,this product has a limitation of 255 prints is it possible to use a database where i can store the images and then do a 1:1 check with this.
i need to deal with at least a 1000 fingerprints,
thanks in advance

Re: fingerprint device 751
There are commands to read and write fingerprint data from the sensors, but we have not tried it here and do not have any examples or tutorials for that.

Re: fingerprint device 751
Can we read the fingerprints from the sensor and save it somewhere else other then the device?
Also is the fingerprint stored as an image or a code?
