- Learn to build an RFID-based door unlock system using an STM32 microcontroller. In this video, we’ll cover everything from designing the circuit and PCB to writing the code and programming the device. Stick around until the end to find out how to get all the project files!
to get the files, you can send a request to ele.wizard.yt@gmail.com
do not forget to start the subject with "PrRq23_RFID_DL"
All the best, The Wizard
Please note that it is indeed possible to store user data in the STM32 flash, as long as one is careful to not write the data in the same memory locations where the program is stored. One commonly starts at the uppermost flash memory location and decrements the memory address as data is added. Of course, this may not be possible for all projects depending on the program memory and data memory size requirements.
Thank you once again for an excellent video!
Lots of microcontrollers have EEPROM built in, such as ATMega and PIC series, although adding serial flash to a project is trivial. I'd probably go with one of the Winbond SPI chips, such as the W25Q128JVSIQ, because they're cheap and I have lots of them in my bins.
I haven't seen your code yet, but for people new to these flash chips, make sure when you're writing to the chip that you 'read' first, 'compare' with what you want to write, then 'write' Only if it is different. Otherwise it's easy to accidentally burn them out.
Great video by the way. I have a box of RFID stuff sitting around that I bought a few years ago and have never used in a project. Maybe this will push me to finally do something with it.
Underrated
Thanks!
Big love for the Super Thanks! You rock! 🫡
Best channel ever
So kind of you ❤️
Hi 😊 .. as always it's nice to watch your video, very interesting, inspirational .. and i will try to follow your way ..
Thanks and Merry Christmas 🎅 🎄
Your lecture is nice, if you have detailed mosfet teaching, please release for us.
You just got a new subscriber. I love your content although i am not going to try this. Maybe my kids will
Wow, awesome, welcome to the channel 😀

Hi, great video! What kind of storage compartments are there in the background?
I like your video content and wish you could reduce your mouse movements and scrolling speed when showing diagrams/code. It makes the video feel a bit "hectic". Maybe it's just me. Also, I don't see a "link to files in description", just a request to email you to get them. Not sure if that's what you intended or not. Thank you for all the good content!
I also love his video content and find him very easy to follow. I would love to take a course on electronics, in person, instructed by him. However, I do share your thoughts on the speed. Maybe a middle ground could be pausing for a few more seconds at the end of each task to show a finished diagram/code. As much as I like the videos, I also love that they don't take a huge commitment of time to watch, so keeping them shorter is a good thing. I have stopped watching a few because they are just too long to fit in the time slot that I have. Keep the video's coming (as your time permits)!
Hi i love you videos even if
it seems that i know about the video and etc i would watch your videos
It would also be wonderful if you could make a video about xbee modules
Thanks
Thanks! Xbee modules are great, I might make a video about them sometime 👌
Nice one , pls I need help in Designing a project work as part of my Final Assessment 🙏
Good luck with your project 🙏
Beautiful stuff great information. Is there any way I could message you? I have a question about a piece of equipment i'm working on
I have a question. I have a project I'm working on and I'm wondering what type of dev board I'd need for a PIC16LF18877-I/ML micro controller
