- RC522 RFID Module. Demonstrate the Elegoo sketch provided in the tutorial covering the RFID Module and expand the sketch to include a Master and User Tag sketch. A beginner's guide to the Most Complete Starter Kit by Elegoo.
Hello everyone, I'm Rick the Tech Enthusiast here with the next Elegoo Lesson. This is the next lesson on my Arduino UNO Series covering the Most Complete Starter Kit by Elegoo. I try to follow the included tutorial and will point out any changes or corrections as I find them.
As mentioned before, I purchased this Elegoo starter kit and Elegoo isn't sponsoring me. I just thought it would be fun to do a video of each Lesson as I was learning the Arduino environment.
We’ll need a few things from your Elegoo Arduino UNO kit. I’ll list the items below. In this lesson we’re going to check out the RC522 RFID Module. I’ll step through the Elegoo provided tutorial, briefly explain the code, and build and configure a simple circuit that is provided in the tutorial to demonstrate the functionality. Then expand the sketch to include a Master and User Tag scenario sketch that’s inspired by Howtomechatronics. I hope you enjoy it.
Parts you’ll need for the tutorial:
Elegoo Arduino UNO R3 board
RC522 RFID Module
Keychain Tag
Plastic Card Tag
Seven female-to-male jumper wires
The next lesson will be Lesson 22: LCD Display

Thanks for watching
THANK YOU SO MUCH!!! YOU ARE SERIOUSLY THE BEST. YOU WILL HAVE MILLIONS OF VIEWS ONE DAY!!! Really enjoy all you lessons!!!!
This is great!! I'm going through the lessons in this exact kit form Amazon right now!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
My module dosent register any tags it dosent detect any tags either
Your code doesn’t register my tags, when it prompts to add master tag, nothing comes up
Awesome tutorial! Is the RFID card safe to use for access control? Its not encrypted and cloning seems to be easy. Is there a better and safer board that would work instead?
The red light turns on on the module, but nothing else happens
Very good 👍
Thank you very much for making these videos, they are helpful, but the 16 minute, line by line walk through of the code, which to a beginner (which is the level ostensibly these videos are for) is sophisticated code, was not helpful. There are too many advanced concepts (F macros, pointers, the optional read RFID function parameters, etc.) to follow along.
It would have also been helpful to include a block logic discussion before the walkthrough. It wasn't clear until the end of the sequence of events.
Then, there is no mention of what to do with this. Although it was straightfoward to add code inside the checkTagID function to trigger an LED (or whatever you want you to trigger), it would have been really helpful to beginners to spend more time talking about this.
And, when the COMs port is closed, the sequence resets. You can however reprogram the cards "in the blind," without the coms port open, and therefore can operate this without being connected to a computer. It wouldve been helpful to clarify that.
All this being said, the elegoo guide on this is useless, and so your video here ultimately was successful and appreciated.
Hopefully this comment is constructive. Thanks.
there is a slight problem whit the code it allows the addition of the master tag into the char array mytags which to me seem Wrong
if (tagIndex!=0){
//Remove existing tag
myTags[tagIndex] = '\0';
Serial.println(F(" Tag Removed!"));
} else {
//Not existing, add tag
myTags[tagsCount] = strdup(tagID.c_str());
Serial.println(F(" Tag Added!"));
tagsCount++;
}
in the else statement which runs if the tagindex is not 0 allows the addition of the master tag.
How to keep value in tag ( like balance, or any number)
Get the dump info to upload keep getting exit error 1... Any idea?
what is the name of the app that reads the code????
arduino ide
Not working
Good explanation but I can't stand the music.
Good point
i agree
same
Lol
Can RFID work with LoRa dragino arduino shield
Sorry, I don't know. I'm not familiar with that Arduino shield.
