Sir i have sensenut sensor... Is it possible to make project with light sensor combined with arduino board... Basically sensenut sensor are used to make a WSN network... So i want to combine wsn network with arduino board
Have a nice day Sir, can i ask a question? I'm a newby to arduino... I have the same LCD display and when I give power to it it shows the same shape as in first part of your video: the upper row is filled with blocks only. I've tried some programs and it seems they are working fine but nothing has been displayed. Of course I've tried to change the contrast but no success. Do you have any advice what should I do? Thanks! Have a happy new year!
For contrast control please use 10k potentiometer. After changing contrast if you have no result. Please connect your gnd pin properly and power not more than 5v. I hope it will be work.
I have a small four wired controller on the back of the LCD and there is a blue potentiometer for changing contrast. Turning it the contrast is changing but no characters wanted to display.
hello sir, just to ask my buzzer keeps on making sound not like yours. when you only tap the rfid card, mine is a constant beeping sound. pls send help and where did you put the wiring for the buzzer? only in D8?
you are seriously awesome. Not an electronics wiz and had to help with my sons science project (which scans books that have an RFID tag into a book bag with a reader.) The sample code is easy to modify and repurpose.
Relay have 3 pins vcc, gnd, and output. Vcc and gnd will be connected with 5v and gnd pins respectively and output pin replaced by buzzer pin. I hope it will be working.
125khz card use here. you can find ebay : www.ebay.com/itm/10Pcs-LOT-RFID-125KHz-Proximity-Door-Control-Entry-Access-EM-Card-0-9mm/231971100274?hash=item36028e1672:g:mCcAAOSwOVpXVnW2
Hey , u should improve this code when the unauthorised card scaned buzzer alarm should turnd on and red lights should indicate ,where green light should indicate when authorised card is scanned....., Also sometimes your code get stacked need to reset Arduino
thanks for your question. Here i use Arduino uno, RFID-RC522 Reader, RFID tag(125khz), 16*2 lcd display, buzzer (for beep), 10k variable resistor for lcd that's it.
❤️❤️❤️
Nice project ...keep making such cool projects !

,are you sure r-w will be grounded?
Hi sir, can you tell me how to register card on rfid reader, if i use identity card (e-ktp) in indonesian which have rfid chip inside?
Thank you sir
Does the tags which comes with Module only work with it ??because I bought few tags separately and they are not getting detected
I think, your new tag frequency doesn't match with your RFID reader. RC-522 reader frequency is 13.56MHz. So your tag frequency is required 13.56MHz.
Razib ji what is the first time showing output after you put many cards near somethin like detector..
what is detector like things ..
How range RC522 can read tag RFID?
How to wire this on mega 2560??

Are you include i2c library for LCD?
yes Sir, #include is the fist line of my code
You may have reversed the wiring on the LCD as I did the first time.
hi... what is a "wiper" to LCD V0 pin (pin 3)?
also, do you use an active or passive buzzer?
Hi, Sir. Can you send the melody that is being played on the video?
i have to connect 4 ground pins including lcd and rfid chip how can i do that i have arduino uno
Arduino uno have 4 GND pins.
@@RazibShahadat arduino uno has 3 gnd pins 2 of power 1 of digital pin
@@techboy1393 No 4 GND pins exist among ICSP pins (6pin together on Arduino Uno board).
hello sir, I want to ask you, why when I uplode the program it says. " download erorr downloads.arduino.cc/packages/package_index.json"?
hello sir I want to know how to add a condition and verfy it on your programm
hello sir, just to ask my buzzer keeps on making sound not like yours. when you only tap the rfid card, mine is a constant beeping sound. pls send help and where did you put the wiring for the buzzer? only in D8?
Are you used my source code ?
hi sir how can I send the data from Arduino ide to php programming ? can you give me an idea for my thesis defend . tanks
Does 13.56 Mhz work for that?
Really great tutorial. If I wanted to use a battery with this, can I use a 9V? I'd like to power and use remotely.
yes you can use 9v bettery
you are seriously awesome. Not an electronics wiz and had to help with my sons science project (which scans books that have an RFID tag into a book bag with a reader.) The sample code is easy to modify and repurpose.
thanks for information. good luck !!!
um it says that the pcloud terms of services do not apply to the file so i can not access it. Can you help with this?
You can try an alternative link.
Razib Shahadat ok thank you I’ve done that
Remember to install the Libraries first!!!
What is the name of this song? I just loved it
I keep grtting a Communication failure. It says "Communication failure, is MFRC522 properly connected?". I need some help on this.
hold the card or fob in the centre of censor while it is reading chip
Got it to work, how add a relay?
Relay have 3 pins vcc, gnd, and output. Vcc and gnd will be connected with 5v and gnd pins respectively and output pin replaced by buzzer pin. I hope it will be working.
Pls make a vedio on laser security system
hi..what kind of card use ??1k or 4 k ? can you recomend from ebay ?thanks for your time..
125khz card use here.
you can find ebay : www.ebay.com/itm/10Pcs-LOT-RFID-125KHz-Proximity-Door-Control-Entry-Access-EM-Card-0-9mm/231971100274?hash=item36028e1672:g:mCcAAOSwOVpXVnW2
thanks allot sir....
Sir you are always welcome
unfortunately I can't open that, can someone help me please
Hey , u should improve this code when the unauthorised card scaned buzzer alarm should turnd on and red lights should indicate ,where green light should indicate when authorised card is scanned....., Also sometimes your code get stacked need to reset Arduino
Good day sir can i ask a question, Can you indicate to me all of the equipment that you use? thank youu.
thanks for your question. Here i use Arduino uno, RFID-RC522 Reader, RFID tag(125khz), 16*2 lcd display, buzzer (for beep), 10k variable resistor for lcd that's it.
In that system sir, you do also with sms module using gsm module? combining with that system
I have no experience on gsm module yet
Can i use breadboard instead of that color green breadbord?
yes sir.
what happen if doesn't use 10k Potentiometer can someone tell me about this
if only connect to the +5v
you must have to use 10k other wise you can not see the date on the lcd
a pot is used to provide controlled volteage in term to set the lcd contrast
my project is really simple i have create rfid student attendance system project without using rtc module
@@syedaiman4420 great
Are you using the lcd or not
What about to create a data base for previous records of attendence
yes offcourse i used it....oooh so potentiometer is really needed for just lcd???
@@syedaiman4420 yes that is mandatory
VERRY NICE
where is the code ardouino?
yeah i need it too but i can't find it :( :( :( :( :(
