can i get that Uart Code at 5:24

[@prabhakarpanchal4227]

Very good information. In my project I am using this pn532 chip using "Type 2 NTAG213 HF RFID NFC NTag Sticker, 40x26mm " NFC. Tag. As per pn532 manual operation distance upto 50 mm. But I my application it's getting upto 20 mm. How I can increase operation range upto 50 mm?

[@rochdimaria]

Can it read smartphone nfc ?

[@SS-Ak47]

Afaik the chip can do that but I'm not sure if the library supports it

[@anggaamalulahli9413]

Why is it that when communicating using SPI, only one pin is declared? What are the other pins used for if not declared?

[@irawanie8635]

the libraries used here is not supported by arduino ide (2.0.3) anymore. upgrade is needed.

[@HowtoElectronics]

Downgrade the arduino IDE to earlier version.

I use I2C, doesn't detect white cards, only keychain and pizzeria card, why?

[@somenathsamanta_8743]

PN532_I2C.h no such file or directery this error is hapening

[@salahxakira]

im also getting this error, if u found the solution please share it with me

4:42 5v ? is 3.3v

[@justsayjay]

Could you use this as a simple on/off switch for a project? Like to turn on a whole device only with an rfid tag? No read / write info. Just to turn on and off a thing?

[@histon]

yeah if you keep a microcontroller running constantly searching for tags, on battery power or powered from your main power rail, then use that microcontroller to switch a relay or something to turn your main device on/off. then in the code you don't check for a specific ID, just if there is a tag detected at all then you switch the relay.

Can you connect more than one module NFC to an Arduino?

[@liswifi]

Your code is for the ATMega processor, but you're running a Nano. Doesn't that use the nRF processor instead?

[@Gamespeare18]

nano? 33?

[@flaviocunha7576]

Isn't this module 3.3 Volts?

[@dibyojyotibhattacherjee897]

Hello, if u do a series on pcb design, it would be really helpful.

[@electronic7979]

Super

[@Luca_040]

you forgot SPI mode

[@SS-Ak47]

Doesn't work

[@ismartalluarjun]

Please make Mit app inventor android app Make video Nfc and RFID all the best thing

[@IbnuHallaz]

nfc.getFirmwareVersion(); return 0 Didn't Find PN53x Module How I can fix it?

[@HowtoElectronics]

Check your connection.
