RFID Control LED
125KHz RFID Reader can read data from RFID tag. It’s can use for some IoT or Intelligent Control System.
This demo will show you how to Read data from RFID tag, and control a LED.
125KHz RFID Reader
RFID Reader connect to D2, D3.
RFID Reader module has internal control IC which make it easy to control. When there’s a RFID tag close to the Reader, then it’ll output the ID of the tag via UART.
You can do some processing in the code for different ID.
The folowing code didn’t judge the ID, whatever tag close to Reader, it can change the state of the led.
Open Arduino IDE, click File -> Sketchbook -> RFID Reader.
Help us make it better
Thank you for choosing Seeed. A couple of months ago we initiated a project to improve our documentation system. What you are looking at now is the first edition of the new documentation system. Comparing to the old one, here is the progresses that we made:
- Replaced the old documentation system with a new one that was developed from Mkdocs, a more widely used and cooler tool to develop documentation system.
- Integrated the documentation system with our official website, now you can go to Bazaar and other section like Forum and Community more conveniently.
- Reviewed and rewrote documents for hundreds of products for the system’s first edition, and will continue migrate documents from old wiki to the new one.
An easy-to-use instruction is as important as the product itself. We are expecting this new system will improve your experience when using Seeed’s products. However since this is the first edition, there are still many things need to improve, if you have any suggestions or findings, you are most welcome to submit the amended version as our contributor or give us suggestions in the survey below, Please don’t forget to leave your email address so that we can reply.
