please can anybody tell me even after connecting arduino with fingerprint sensor and using Adafruit library of Fingerprint sensor. I uploaded the code ......there was no error ,it was successfully uploaded but while seeing on serial monitor ....it shows fingerprint sensor not found.Even it is successfully working with SFG demo software . I am using R305 fingerprint module. So please anybody can tell me about...why i am getting this error??
Where did you find the information that the Adafruit fingerprint library works with your sensor? Adafruit made the library for it's own product that uses a sensor of the ZFN-20 series. Except a similar optical component I cannot find many similarities between the two products.
A link to the product you're using might help...
