I just bought this fingerprint https://dfimg.dfrobot.com/store/data/SEN0348/SEN0348_768x512.jpg
So where does it store the fingerprints ?
Does this fingerprint module have its own storage(memory) or fingerprints are saved to arduino ?
It stores them.
Thank You, is there any library to control this ?
Can someone please help me how to connect this ,to arduino uno ?
I found sheme , but there are diffrent colors and wire order
Check pictures below
the color is just a plastic coating over copper. follow the pinout, not the color, or make your own header with appropriate colors. I keep heat shrink around to amend color coded headers that do not match my color scheme
Thank you! Works
Now i got another problem
I connected it and it detects now fingers , but i didnt even touched it
