Re: Fingerprint unlocking electronic lock based on ESP8266
What I mean is that from the outside it looks like the electronic lock is unlocked by the fingerprint, but in reality it is unlocked by other methods. For example, if an invisible button is added to the place where the finger is placed, it looks like the fingerprint is unlocked from the outside, but...

Re: Fingerprint unlocking electronic lock based on ESP8266
I wanted to find a way to replace this recognition and make it "fingerprint recognition" with something else. Sorry not quite sure what you're asking? Do you have a suggestion for what "something else" might be... a touchscreen isn't going to be able to read a fingerprint, but you could, for exampl...

Fingerprint unlocking electronic lock based on ESP8266
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, ...

Re: MFRC522 RFID-Reader Class
Hi there, I came to your topic from someone's recommendation. I've seen card reader projects using Arduino, but I want to finish it with ESP32, is there anything I should be paying attention to?

Re: MicroPython how to achieve communication between ESP32 + RC522 (read and write cards)
See this thread which seems quite a compact driver. I also looked at this Arduino library which is pretty hairy: nearly 2K lines of C. Clearly there is a lot more to RFID than meets the eye. Thank you so much! You are really a very kind person. It really helped me a lot! Once I'm done with this pro...

Re: MicroPython how to achieve communication between ESP32 + RC522 (read and write cards)
RC522 is an SPI module, so you can easily interface it with SPI pins of ESP32. You need to download its third-party library and you will find ready to run examples to test it out. Try those examples and share your results. Can I ask you for a link to a third-party library? I'm not quite sure if I c...

MicroPython how to achieve communication between ESP32 + RC522 (read and write cards)
I have a module of ESP32 with Micropython firmware, I want to try to connect with mrfc522 to read/write cards, I have read some related articles on the web, https://www.instructables.com/How-to-Di ... gh-LCD-Wi/
but not using Micropython, I hope someone can give an idea.
