Nice video again. What do you use as a power supply for the different voltages? Which kind do you prefer or recommend? Merry Christmas 🎄

@20.12, Had figure out why my sensor does not work, indeed the PN5180 need 5V from the ESP32 vin pin. The PN5180 library did not mention this in the example code.

Thank you SO much for making the PN5180 library! How does it handle collisions (multiple tags?) I actually have a few of the boards lying around since your last video on it, but I couldn't get more than basic testing working. Maybe I should get back to tinkering with them taking hints from this video.

I wonder if it's worth doing a video on converting SPI (and other serial protocols) to/from RS485 so it can be sent over very long Ethernet cables, depending on data rate SPI can be quite limited on how far you can reliably send it and using RS485 makes best use of the twisted pair cable. there's very easy/cheap to use RS485TTL converters available from the usual suspects.

Hey Good Job Playful Technology and I Have a question can we make this setup with multiple rfid tags (reading 5-10 tags at the same time) ?

Would you recommend these readers for a project that is reading the difference between two different pets, wearing the rfid tags on their collars? I'm making a project where I want to be able to passively read the difference between two pets to open and close a food bowl. The rfid reader would be somewhere near the bowl that is going to be opening and closing. Do you believe that these rfid readers would be able to read a moving entity that is at a range of 45 cm away from the reader? If not, is this project even possible using rfid? I've been debating between bluetooth and rfid but I really like the idea of having a passive tag.

You always have such joyful projects and in depth coverage. While its a shame the code and things now has to be behind a paywall, I think that you have at least demonstrated enough information where a person on a low income could replicate the project with what you have provided and a little research and study and have managed to strike a great balance between the new and the old methods. I think you have and continue to be of great service to others and can also get some wages for your dedicated work. I still find the channel fantastic and your uplifting demeanor and fun projects really make this channel a joy!

Hi. I am wanting to use the pn5180 board and arduino uno to create a feeder that only feeds one of our calves. I can't find the small sticker tags that you can get for the PN532. The cattle have ear tags by law and I was hoping to use a sticker tag stuck onto the ear tag. Have you seen these available?

Couldn't the Rest wires also be commoned? In fact for something like this you could possibly common the busy lines as well although I've not looked at the PN5180 datasheet yet.

How are you? The content is very good. Is it possible to share the pinout/connection diagram?

Awesome video as always! I have some questions.. Is there a way to adjust the reader sensitivity like in the mfrc522 library? I am worried that the reader might be too sensitive in some applications- having readers too close together could cause problems I assume for some puzzle setups! Also, do both the 5v and 3.3v need to be connected for the module to work? Lastly, I think it would be better for most escape room puzzles to have an automatic reset as opposed to having a dedicated reset card. Automatically resetting after all of the cards have been removed is something I struggled with when making some mfrc522 puzzles because the library allows the reader to detect when a new tag is present, but doesn't have a function for detecting when a tag is removed. Is this something you have tried using the mfrc522 or pn5180 modules?

You can detect if a tag was removed by polling the reader and comparing to the last reading, if the last read was an ID and the current read is nothing, you know the card was removed. He shows the code for this at 50:49 Resetting automatically has the drawback that players can reset it themselves, which might be unwanted. But when this doesnt matter its definitely the simplest option!

Hey, i have the problem that my mfrc522 reader read the card a few times and then stop working. I have to reset the whole thing. Any idea?

Great!

Good Information. As you mentioned in Titel "Long-range RFID", but the PN5180-NFC sensor only communicate with NFC tags, is it possible to use same sensor for RFID ? Thank you

Great video! - Thanks! you've used RJ45 breakout boards to carry the signal lines to the ESP32, I wonder, what is the maximum range you can go with the cable without losing the signal quality ?

Is their any way that i can send data receive data from under water esp32

I have found that the sensors will work on 3.3V and don't need the 5V. YMMV

Do you know how good the PN5180 can detect RFID/NFC rings? I used a PN532 and it could only read it if it was virtually touching.

@PlayfulTechnology

2 жыл бұрын

In my experience, those rings are pretty useless because the metal of the ring interferes with the antenna of the RFID chip itself... I've only ever been able to get read range of a few mm too.

Hey man, cool video. Do you know any anti-metal tags that can read through a metal table ? ones I bought work only on metal surface. Want to place the PN5180 under a metal table.

@PlayfulTechnology

3 жыл бұрын

I'm pretty sure all the RFID technologies I'm familiar with would not work if attempted through a metal surface - it requires electromagnetic coupling which is achieved through a tuned antenna, and the metallic surface would interfere with that. It's possible that an active RF transmitter at a suitable frequency might work, but that would obviously require battery power in the portable part of your prop.

You would need to have a device with 3 more pins, for NSS, BUSY and RST. (The SPI lines are shared). (If you don't have spare pins you can buy port expanders). Then in Alistair's code you change the number of devices, and specify the pin numbers in the nfc array

READY TO JOIN PATRION, but first... Hello, I am in the Philippines & just getting started with all this. I just bought an Arduino Uno (with 3.3v) and 5 RC522 rfid sets.

I know $10 doesn't seem like a lot there, but here that's 1 days wages, So it's better to check first if I can do what I need to before I spend so much. Thank you

Thanks. Let’s say you have a bunch of cards that you want to be readable by multiple readers without having to program in the UID of each card for each reader. You would want to write a block of bytes to each card with its name, so that any reader could read the card without having to know its UID, and also worn out cards could be replaced without having to reprogram the reader.

I wondered this too but it looks like there is a separate 9th wire, presumably GND, going to each of the readers ;) Maybe you can use shielded JR45 connectors and connect the shield to GND, then you get away with just one cable.

Hi @@mazemakes , I believe I saw it too, but hoped it to be wrong :) I was wandering if only 5V could be supplied (and not also 3,3V) and then use the 5V for 5V (of cource) and a stepdown resistor (? ohm) at the PN5180 module side (or a specific stepdown module) for the 3.3V input. Then 8 wires are enough, without going with the shielded wire... :-)

@@mazemakes Hi, Yep you are right :) I wasnt aware of that. I have read a little about it since your post. Maybe setting 2 resistors up as a voltage divider, where the PN5180 specs determine the mA and thereby the resistors? I found some specs specifying 250 mA as max and limiting value 300 mA. So if 250 mA is max and 5V, the total resistors will be 20 ohms. Then the resistors ratio must be 3,3V/5V = 0,66. Giving R1 = 20 ohms x 0,66 = 13,2 ohms and R2 = 20 ohms - 13,2 ohms = 6,8 ohms. Is that correct?

As @TheKsbdude said, the PN5180 is capable of decoding both ISO15693 and ISO14443 tags, and they normally come supplied with one of each type - I only demonstrate the ISO15693 in this video, because if you only want to use the shorter-range ISO14443 there's plenty of examples using the cheaper MFRC-522 boards instead.
