A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. We also toss in a Mifare Classic 1K card! ( You can get more tags from us here) If you want to stack another shield on top or below, check out our stacking headers that allow pass-through stacking. For using the I2C interface with Mega R2 or earlier, two wires must be soldered as the I2C pins are in a different location on earlier Megas.Ĭomes with: the Adafruit NFC/RFID PN532 shield including a tuned 13.56MHz stripline antenna, 36-pin 0.1″ header for attaching the shield to an Arduino. Compatible with any “classic” Arduino – NG, Diecimilla, Duemilanove, UNO – as well as Mega R3 or later. It is also easy to change the shield over to SPI where you can use any 4 digital pins by shorting two solder jumpers on the top of the PCB. You can adjust which pin is used if you need to keep digital #2 for something else. This means you don’t have to sit there and ‘poll’ the chip to ask if a target tag has been found, the pin will pull low when a card, phone, etc is within range. Digital #2 is used for “interrupt” notification.
I2C is the default, as it uses fewer pins: analog 4 and 5 are used for I2C (of course you can still connect other I2C devices to the bus). This shield is designed to use I2C or SPI communication protocols. You can easily attach the shield behind a plastic plate with standoffs and still read cards through a (non-metal) barrier. The Adafruit shield was designed by RF engineers using the best test equipment to create a layout and antenna with 10cm (4 inch) range, the maximum range possible using the 13.56MHz technology. It can also work with any other NFC/RFID Type 1 thru 4 tag (and of course all the other NXP MiFare type tags) We carry a few different tags that work great with this chip. You can do more stuff with NFC as well, such as communicate bi-directionally with cell phonesīecause it can read and write tags, you can always just use this for RFID-tag projects. It is an extension of RFID, so anything you can do with RFID you can do with NFC.
#Iclip rfid shield set Bluetooth
Sort of like a very short range bluetooth that doesn’t require authentication. NFC (Near Field Communications) is a way for two devices very close to each other to communicate. If you want to do any sort of embedded NFC work, this is the chip you’ll want to use! It can pretty much do it all, such as read and write to tags and cards, communicate with phones (say for payment processing), and ‘act’ like a NFC tag. The Adafruit NFC shield uses the PN532 chip-set (the most popular NFC chip on the market) and is what is embedded in pretty much every phone or device that does NFC. We’ve taken our popular Adafruit PN532 breakout board and turned it into a shield – the perfect tool for any 13.56MHz RFID or NFC application. PN532 NFC/RFID Controller Shield for Arduino + Extras. Here’s a video guide to getting up and running with the Adafruit PN532 NFC/RFID Controller Shield for Arduino! Video on YouTube and Vimeo.
