In ur circuit diagram the sd card module has 8 pins (instead of six) and the RTC Module 4 pins (DS1307 TC and not the DS3231 ) which confuses me alot. I am not sure, if I should trust the diagram or not. Wouldn t u mind sending the corrected version of the diagram?
Loved this project sir. Looking forward for doing this project for our Final year project. If possible would you please provide the simulation part of it?? Thank you.
Issue : Soft Version: 0xFF (unknown),probably a chinese clone? Geting RFID Software version 0xff and not able to read by RFID Tag if I connect SD card module and RFID reader same time but on when I use individually both are work fine and that time RFID give me 0x92 but at both same time RFID give me 0xFF... Any Suggestion ?
I'm wanting to do a project using 6 sensors that output frequency in the 100khz range. I'd like to take the device to a location and record the frequency output of the 6 sensors at that location and also the location # using RFID, and store that data for transfer to a desktop. Is that to ambitious for something like Arduino?
Sir i want 2 help 1 i want green led blow ( you are welcome) mode how access / code and after code can cable remove and power to dc jack?? please help sir
Initializing SD card...Wiring is correct and a card is present. Card type: SD2 Could not find FAT16/FAT32 partition. Make sure you've formatted the card
Thank you for your hard work I have one question about the code it works perfectly but If what should I change if I wanted to change the ID numbers to make as names and also could we do access control like certain ids are only allowed to enter? can somone help me?
You need some clock to detect the time. DS1307/DS3231 acts as a clock. You can't use time from Arduino as it doesn't have record of time, it has only millis function timing. Moreover when arduino and DS1307 is turned off, the last time get stored in rtc memory. This function is not supported by Arduino.
@@HowtoElectronics sir please make project on rfid and finger print sensor both with arduino if finger defined OK then led on and card defined id scan led on
Great project and tutorial my friend! This is our project in school. Can you help me with this? How can you add SMS feature using SIM800L? Thank you my friend.
Thank you so much! Most tutorials are misleading with positioning of the 330 ohm resistor. Thanks for showing the real wiring at 2:58
Should we use 330 ohm 1/4 watt resistor or 330 ohm 1/2 watt resistor
@@dlalitha5428 hi, i think the 1/4 watt is ok. i used it and it worked just fine for me

Will it still working when power supply is coming from a power bank
Useful project 👍
Not displaying anything after initialization is done
Which software did you use to simulate the circuit diagram
the 330 Ohm resistor on miso pin of the rfid reader, can I use a higher value resistor?
A very good project for Attedance Management
Thanks Subbu bhai :)

Try with some other value resistor manually.

Can we make this project without using DS1307. Why can't we use time from arduino.

@@HowtoElectronics Thanks a lot for the answer. I get your point to use the clock.
Thank you sir. Will you tell the procedure?
sir can modify with 5 cards
Can we used 8gb memory card instead of 16 gb?
Sir, after the 'initialization done' I couldn't scan the rfid cards on the reader module.
please reply sir!!
Make sure to check the serial monitor logs.
Make sure SD card connection and Rfid connection is correct.
The connection is correct sir! And the serial monotor log showed 'Initialization done'
I did the project on a pcb sir.
I solved it sir!!
Sir the code giving error ... No matching function for call to date time...can you solve this problem sir pllll
