I recently saw an article about a simple fingerprint unlocking electronic lock project article, and I really want to make a change according to this article. The article is using a fingerprint sensor module, and I would like to change it slightly here. A fingerprint sensor module is not very cheap, and I wanted to make the most of the resources at hand to complete the project. So I came up with the idea of using a touchscreen display to simulate fingerprint unlocking. Although the actual touch screen doesn't do fingerprint recognition, I wanted to find a way to replace this recognition and make it "fingerprint recognition" with something else.
I wonder if anyone can understand what I'm trying to say?
