Nitgen Fingerprint Scanner with Arduino

Development Boards Arduino

I am trying interface the Nitgen Fingerprint Scanner with an Arduino. I have an RS232 to TTL circuit set up, but I am not sure if I am writing the code with the Arduino correctly. I need to send commands seen in the attachment, which is a series of bytes such as 7E 00 00 00 01 … I have tried printing those hex numbers like this Serial.print(0x7E) and also Serial.print(0x7E, BYTE) but have had no luck (I tried with all of the following numbers but didnt want to post all of them for example purposes). I am trying to get the device to enroll a user for startes. Any help with this code would be greatly appreciated! I will post the specific code later if needed.

Thanks! :slight_smile:

The attached code is the example code for enrolling the user

Hello, i am trying to understand how to make my fingerprint in use. I am sure about my circuit but i am very confused with the code. I cant see your image. Could you send it again?

thanks in advanced
