Throughout this project, we will be showing you will learn how to put together a circuit that makes use of both the RFID RC522 reader and a 16×2 LCD.
We start by showing you all the steps required to connect these circuits to the Raspberry Pi’s GPIO pins. We will also show you how to test each circuit so that it is working as it should. This helps ensure everything will be ready to be utilized in our RFID attendance system.
In the second part of the tutorial, we will walk you through all the steps to setting up a database. We will also be writing Python scripts that will talk to the database to mark attendance for individual RFID cards.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. 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 code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. 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. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
