Very good tutorial, I 'll try this weekend.. Only a question if I want write something into the key?

[@chimpofm]

great video. can the rdm630 be used to write a card id to a fob, like those blue clones?

[@mindracing]

Really great, easy to understand and very helpful. Please can you tell me what wire and how many windings you used to make your own antenna?

[@AEMgamingyt]

Hello, Would i be able to use this with an arduino mega? how would i change the TX & RX pins in the code? i believe for the mega you have to use pins 10-13.

[@gnormhurst]

Very nice work! An excellent survey and report. I noticed that you detect the end of the message by looking for the value '3'. But what if part of the message contains a '3'? Wouldn't that confuse it? Also, the transmitted values you are calling 'bytes' seem to be 4-bits each. Bytes in my understanding are always 8 bits. 4 bits (one hex digit) is sometimes called a 'nybble' but never a byte. Although I suppose the library maps these nybbles into bytes in the processor, so from the code point of view they are bytes.

@Michael Schoeffler Thank you for the interesting tutorial. Do you have any recommended full tutorial (video, text ...) for designing a tracking and monitoring system using RFID (preferably in python? Thank you in advance

[@gallib2147]

thanks helped me clone my gym rfid card:) to a card

[@washingtonoliveira3523]

Qual a maior distância do sinal do rfid? Tem como fazer a uma distância de 1 metros?

[@83speegy]

Nice tutorial. Could you create a video to show how is it possible to write an RFID tag? How is it possible to copy the tags? It Will be very helpfully.

[@3mariusx]

83speegy this is my question too

[@mohamed-jt7eu]

@@3mariusx did u guys find a way to clone the tag ?

Nice

[@shiewweilun2810]

Hi, when i upload the code into arduino pro micro, there is no initialisation. can someone assist me in this problem. thank you.

Gutes Video Kurze Frage wie viele Wicklungen hat deine eigene Antenne?

[@casasearl]

What rfid reader to use for wider range? I wanted to make a pet feeder that opens the bowl if the pet gets near the bowl

[@Siddharth_Sharma7711]

You can use " active tag or uhf tag ..

[@davelodia9157]

Sir Can you share the code out put txt file will show date and time?

[@zolution2839]

greetings, thanks for your contribution, a question. You say what hex values encoded to ascii, then what does the arduino, hex or ascci receive. Thanks

[@szekelymihai]

ssvalue reads in decimal, but can be converted to whatever format you need - Serial.print(ssvalue,HEX); or Serial.print((char)ssvalue);

[@jumbo999614]

How to use it with ATTiny85 instead of Arduino UNO? I got error while compiling the code.

[@stevejohnson4618]

Can rdm630 read animal tags?

[@mostafaaliael-din4814]

Hello , i see some sources that says it can read 134.2khz I have some microchips that has 15 numbers code and from what I found it seems like RFID 134.2khz , can this reader read it?

[@joselucas9398]

Could you tell me if you know any rfid that could read a card from like 40-60cm?

[@jolyonjenkins947]

Do you know what inductance the coil should be?

[@DOMINATOR-ou8nz]

I guess, you can find the answer in RMD6300 RFID-IC datasheet

[@mesadirectivaboskiasur5935]

Excellent video. I have a question, how to calculate the turns to make the coil? What size is the coil?

[@3mariusx]

Mesa Directiva Boskia Sur it is available to buy it

[@mikerosal7393]

I got problem with this line of code : long tag = hexstr_to_value(msg_data_tag, DATA_TAG_SIZE); It said that this line of code are "invalid conversion from 'uint8_t* {aka unsigned char*}' to 'char*' [-fpermissive] " Can you resolve this issue, please

[@calroure]

I have the same error, I'm using an ATMEGA 1284P and it seems no compatible with this program, have you found any solution for this problem ?

[@bspringer]

Can someone tell me why neither your code nor the one from another guy works for me? The reader is brand new so that shouldn't be the problem. I also hold the tags directly in the antenna so that should not be the problem either Board: Arduino Leonardo (atmega 32u4, 16MHz) What I found out: The Serial connection between the Arduino and the RDM6300 doesn't get established. The Serial connection between the PC and Arduino works. The dips in the brightness of the control LED are visible so the antenna and the recognition of the tags work. So can it be the software Serial or the chips itself?

[@bruno_ricci]

What voltage is it operating in? Are you sure you are connecting master TX with slave RX as ir should be?

[@bspringer]

@@bruno_ricci I assume the issue was Software serial on the Leonardo. I used hardware serial (Serial1) instead and everything worked.

[@Ardey95]

​@@bspringer Hi there, I'm having exactly the same problem you had with a Leonardo. Can you explain to me how you solved it? This is my first Arduino project so if you could detail it for me, it would be awesome.

[@bspringer]

@@Ardey95 I can't quite remember the exact issue but from my answer above I assume that I configured SoftwareSerial incorrectly. The Leonardo - different from the Uno - has Serial or Serial0, which is the USB Serial, and Serial1, which is on the GPIO pins 0 and 1. The Uno only has 1 Serial port. You could run the Serial Passthrough example and check whether it sees the tag once you hold it into the antenna. The RDM6300 should read the tag over and over once you put it there whereas the RDM630 only reads it once - when you put it near the antenna.

[@Ardey95]

@@bspringer The thing is that I'm trying to connect it to digital pin 6 on a pro micro board. I tried other pins as well, but after initialising SoftwareSerial, when I check if it is available, it's always false

[@igeorge688]

First comment is reading. It continuously read if you do not remove the tag. It is annoying. Normally should stops after first reading. The second issue is about display. I would like to have a full 14 bytes display beside the calculation to decimal. I want to store all the bytes on a eeprom as hex bytes and not decimal number. Can you add a line to display the hex bytes readed ? thank you.

[@igeorge688]

Correction, I see the hex value of the tag. The only issue remain multiple read.

[@jonathanleslie9100]

this is a great tutorial, but I"m looking for a reader with a much bigger range: say 1-5 meters. My idea is to have the RFID card in my pocket and not have to take it out to trigger the arduino. Can you recommend a solution?

[@Shocker99]

Yes. Read about antenna design. Distance is directly proportional to loop size. The distance shown here is approximately correct for the loop size.

[@jonathanleslie9100]

I really just want to repeat what is going on with my car and its rfid to unlock the car door

[@jonathanleslie9100]

@jon b whatever it is, I want to be able to detect my car keys from about 2 meters away and program a raspberry pi or such to open the door to my house can you recommend a car key reader like that?

[@jonathanleslie9100]

@jon b I program guidance systems for a living and develop AI algorithms for best fit analysis in deployment of limited resource for maximum gains. I've worked with DSP's and programmed FPGA's to recognize wave forms of carrier frequencies over gated signals when time constraints demanded It. Please don't embarrass yourself further with baseless assumptions about my background. It makes you look like an idiot. If you don't know what the transmission of my key fob is that acts as a proximity switch to allow me to unlock my car door by touching the handle of the car door just go away. Just to let you know, the signal is already produced or echoed back in the case of a RFID, and making a device to recognize the exact digital pattern of my FOB is no less secure than my car door already is. In fact since its hand made and keyed specifically to my FOB, the idea that someone would think my house door works that way is ridiculously improbable. ( Along with my masters degrees, I have a undergraduate degree in Mathematics. The issue here is to know what the XMIT of my car door FOB is write a Rasberry PI program to recognize what that pattern is and when it does it arms the unlock button. NOW, I haven't taken the battery out of my key FOB yet, but I"m 90% sure that if I do I could still have my car unlock automatically. That would confirm my belief that the unlock feature that only works when I'm within 1-2 meters of the car and requires no button push on the fob to open the door is in fact RFID as RFID is completely passive. (You can look up passive vs active RFID on your own time.) Having the reader of the key FOB in the vehicle gives lots of room for a high gain antenna to be built into the door so that it could reach the necessary 1-2 meters vs the systems that require you to hold a card up to the reader within a centimeter or two (like the way the disney magicband works.) So in short, Shit or get off the pot answer the question or go away and find something you know about to talk about.

[@jonathanleslie9100]

@jon b "With those supposed credentials , you should be able to figure it out" How do you think someone with my credentials figures things out? we ask questions, we research how things work and add onto them. Why do you find this so confusing? My instinct tells me you haven't been able to figure out much in the past or else you would know exactly why I'm asking the questions I'm asking. Really Now, you are embarrassing yourself.
