bro how did you connect na mfrc522 into the breadboard? im having a communication failure and it;s loose don;t know how should i connect it

Best video for this build I could find. Typing the code in as you go helps with learning also. Great video

Nice one, , have looked for this one with a good code explanation, , Iam a Mechatronics engineering student, , and I enjoy Mechatronics

Ive been watching this many times your explanations drives clear and easy to understand thank you bro keep it up hope you can provide more, , ,

For those constantly getting a timeout error, note that you should keep the tag on the reader until the output is completed - either that, or you may have a connection issue

Thanks for this video bro, you explained very well for each line of code. It was very helpful for someone beginner like me to learn Arduino programming. Please don't stop making a videos and keep teaching us👏 may god bless you.

How fast can the reader detect the tag? I want to try using this to uniquely identify my rc cars as it passes by it, which can happen really quickly.

How many concurrent tags can it detect as once? I might have multiple tags nearby it.

Do you have alternative solutions for my use case if this isn't suitable?
