I have all setup but RFID and SD Card both same time not work due to common SPI pins My RFID have 2.0 Version which not allow to work any ssalve like SD card any suggession?
Hi brother I am trying to make this project but I am facing some issues SD card reader I am connected to Arduino and everything is fine after connecting RFID and RTC nothing happened check on the serial monitor shows that an SD card was installed but RFID is not reading RFID module I connected Arduino uno and checked serial monitoring is working fine All these modules are connected rfid not reading Please give me some tips on solving this problem Thanks
Hi brother I am facing some issues with this project, please help me The Rfid module and SD card reader are not working same time I just contacted the individual both modules are working properly Please give me some tips Thanks
Sir... I face with these problem... "initializing sd card... initialization failed" And "Couldn't find rtc"... I use Arduino mega 2560.. Sd card module has SCK pin.. And rtc is DS3231... When I upload the sketch of yours I face this problem... Can u tell me the pinout for arduino mega... I NEED TO SUBMIT THIS PROJECT WITHIN 3 DAYS...ITS VERY URGENT AND IMPORTANT.SO PLEASE HELP ME SIR... THANKS IN ADVANCE 🙏🙏
sir, i want to ask you, i have done all this wiring and every part well done, but if i run all project , a part like rfid or rtc not identify, please give me solution:(
@@technolabcreation RC522 and SD card works okay individually. I take out the MISO wire from RC522 and the SD card works. Same thing vice versa. Any thoughts?
Anyway, has anyone tried this? It does not work !!!! 2 SPI devices cannot work like this !!!! Fake project!!!!! After SD initialization rfid cannot work
I was not expecting to find a video with such good explanation. Hope the best for you.
Best video regarding electronic
Thank you to this videoke , finally i found a clear explantion regarding RFID attendace system using arduino. Gby
Jabardast bhai!!! 😍
It's very helpfully and awesome
this is work, thanks sir
Best video regarding
Very good... Keep it up 👍👍👍
Thank you
Bhut ache sirji
Thank you
Awesome project, but in editing I do suggest monitoring your audio for overlapping and loud volumes.... Thank you so much for this
Ok l Will consider
Awesome video sir 👌👌👌👌👌👌😊👌👌
Thank you
Thank you. Good Project.
Thank you
awesome project

Gud...And also please make if any student absent when sent SMS to principal and parents.
Okk I will make it
very nice
Thank you
Nice
Thank you
Sir, for this project can it program the user's name for each rfid card?
Thank you .nice work
Can you please make a video about the same perose but storing the data in Google sheet. Thank you
Ok i will try
@@technolabcreation
Thanks you are amazing.i really need it soon
how can I add display what's the connection for that?thanks ahead
Can I use the SD card module to save data at 1kHz?
can you give me programme with capteur ultrasonic when it work ,it will save it with module rtc and sd card
Sir how to assign name against each UID.
Please help
👌👌👌👌
Thank you
😍😍😍😍😍😍
Thank you
My project is to save the time when something turns on and the time when it turns off
can i use this with arduino mega?
I have all setup but RFID and SD Card both same time not work due to common SPI pins My RFID have 2.0 Version which not allow to work any ssalve like SD card any suggession?
same here, do you did fix it? can i know how you fix it because this arduino project is my final year project at my college.
Thank you for this video. But i want to verify the user UID from SD card data. What can we do. Please give a solution for my project
Modified the code accordingly
Can we make this project wireless using batteries and the upload the data to excel sheet
Yes
What pins to use on Mega? Please answer.
For spi, you can use the icsp 6 pin header near the chip, for i2c you can use pins 20 and 21 for sda and scl
#include // for the RTC error in this area cabu help me im a beginner
Hi sir i have made all the connections properly and initialization is done but RC522 is not reading cards at all..plz help me out of this
Hi brother you solved this problem help me I am also stuck
Hey bro. I have one doubt... U used RTC DS3231 module.. But in code u used RTC_DS1307 class for "rtc" instance... Can u clear my doubt!! Please
Code work for both you can use anyone you want
@@technolabcreation tq bro❤
Hi brother
I am trying to make this project but I am facing some issues
SD card reader I am connected to Arduino and everything is fine after connecting RFID and RTC nothing happened check on the serial monitor shows that an SD card was installed but RFID is not reading
RFID module I connected Arduino uno and checked serial monitoring is working fine
All these modules are connected rfid not reading
Please give me some tips on solving this problem
Thanks
it is SPI conflict.... i also don't found yet how to fix it but please tell me via email if u know how to fix it.... it is my final year project too
how to design a rfid based attanedence system and the data will store to a local web server please help me
Use esp32 or nodemcu in place of arduino and create a local server for storing data
@@technolabcreationyes best way..and connectesp32 or nodemcu to the internet and store the data to a cloud server
Hi brother
I am facing some issues with this project, please help me
The Rfid module and SD card reader are not working same time
I just contacted the individual both modules are working properly
Please give me some tips
Thanks
Wire them properly, it should work
Sir the code isn't working anymore for me. May I ask if you would resend it again?
Okay give me your email id

can't help much but try ask chatgpt for fixing the coding
Please i need help with my project
Okk.. Contact me through email
conflict MISO line even with resistor.. Fail
Sd card module and mfrc are not working at the same time...after making connection more than 5 times it still becomes failure
@@subhadipdeb3817 same
yes u right.. this is bait 😳
I figured it out. I made my PCB out of it.
@@philipecaing1273 i use another arduino, and it communicate with software serial, everything working fine and no conflict 👍

Check connection of rtc and rfid again
@@technolabcreation Oke, let me try
@@technolabcreation can you help me for this project, I needed, please..
Send me screenshot of your error on my email
@@technolabcreationsorry, what is your email?
I need help. Initialization failed
Check your connection of sd card module
Don't add any resistance... Just do all connection again.. May be your any wire is not working
@@technolabcreation RC522 and SD card works okay individually. I take out the MISO wire from RC522 and the SD card works. Same thing vice versa. Any thoughts?
@philipecaing1273 Hi brother just explained how to solve this problem
I am also stuck with same issue
Please help me
@@gireeshkumarg2444 stick the other module to an analog pin. use ADC. add capacitor afterwards.
Anyway, has anyone tried this? It does not work !!!!
2 SPI devices cannot work like this !!!!
Fake project!!!!!
After SD initialization rfid cannot work
This is not fake project and yes it is possible 2 SPI devices can work together.
