I am in the process of building a system that uses mini NFC stickers on practically everything I own (really only on all my stuff that creates clutter) and NFC stickers on a shelf of plastic bins. Sort of like a wall of bins like the Mythbusters had, but not nearly as large. The idea is that I am building an app for my phone that I can take a thing that I have put an NFC sticker on, scan it with the phone, put the thing ion a bin, scan the bin NFC sticker with the phone, and then add a name and description for the thing and now if I need the thing, I do a search in the app and it tells me which bin it is in. Doesn't matter what bin I out things in, to clean up, I just need to scan the stuff and put it in a bin. Waiting on the NFC stickers to show up from China and then I'll be off to the races.
Awesome - sounds like a really interesting project Sevil.
Important troubleshooting tip: If your having trouble reading cards despite following the steps in this tutorial, make sure that the 3.3 volt input and GND pins your reader board are hooked up to the 3.3 volt output and GND pins on your Raspberry Pi Pico. If you go to 19:36 in the video, you can see that the wiring is slightly different than what was shown in the wiring chart at 14:02. If you look at the leftmost white wire and the 3rd wire from the left (gray), you will notice that they go to pins 36 and 38 respectively.
Very informative. Also learning when things go wrong. Thanks
Thanks Nigel!
Hey Bro, very nice video.
I coppied exactly, what you said on my pico and also connected the wires like the table on you repo but it doesn't work. Could you help me pls?
Loving your channel. Thanks for the content!
Thanks Ron!
Hello Thanks for the video. I already made some test with the files you shared and all of them works fine. On my case was required keep hold the card on the rc522 and dont move the card until finish the action JOB (create, reade, erase). So i think that is the hint because i used the same hardware like you and again, thanks for the videos.
Thanks Adrian, I did find these a bit fiddly to begin with, so thanks for the tip
hello, it was very good video but do you have ide about why it don't work on pico w yet?
Hey can you upload a tutorial on how to setup the wires pls
Perfect video! Kudos!
I'm following along, and I did the exact same thing, but it doesn't work. :/
the line:
(stat, tag_type) = reader.request(reader.REQIDL)
always result in stat == 2 and tag_type == 0.
I've changed the wiring, the sensor, the breadboard, another Pico, but it's all the same. :(
I'm using Micropython 1.23.0.
Do you have any tips?
Hi there, do you know of a way to save the data from the block in a way that can be used to activate something instead of the UID? I cannot figure it out to save my life using your code. Works great but I need that modification to trigger a solenoid from the DATA block, not the UID. Any ideas? Will be glad to buy you a coffee if you can help me! Thanks
Hi, I connected my RFID reader like so: sck GPIO18, mosi GPIO19, miso GPIO16, sda GPIO17, rst GPIO22. I'm using the library from the repo from your description, but it does not seem to work. My Pico uname()[0] is rp2. Do you have any idea what can I be doing wrong?
Try swapping the miso and mosi cables at one end
Hi Kevin, thank you for sharing this! I am planning to use the low frequency reader 134 kHz for livestock but I am struggling to find modules for it. Plus the ones I found are of 9v so not sure if it’s gonna cause any problems with the Pico.
is only read? how i can write them? i'll thank you answer
I made an amiibo hack tool for making maps in links awakening
Im sorry, but what the heck was this whole video about? Ive tried every code you showed but nothing worked! Every time I placed my card or tag on the reader, it ended with Auth Error..
Well all I can tell you is that it worked, as evidenced by the video! What model of card, reader and Microcontroller are you using?
All good, but lost you at Moto copyrighting 'little-endien'.
Really? What did I do?
