I got a question that I think you could help me.
I have an Arduino project with the Fingerprint module. After i finished it, I want to register a new fingerprint to my project but I want to do it without connect it to the computer. But I want to register it through Android Application that I made it by following your tutorial on youtube. After that I am confuse at how to write the Arduino code ... So I really hope that you can help me to finish this project
Btw this is the video that I watched
"Create a bluetooth app and control the arduino"
