This little code shows you how easy you can use a RFID Modul in combination with a Keyboard function (from Arduino Pro Micro (ATmega32U4)). Freely usable for all with the exception of military and ...

An Arduino Nano or a Micro might be the best options If a small board sounds like the most appropriate choice. ... RC522 RFID module, and TFT display module.

Learn to build an RFID based attendance system using Arduino with step-by-step instructions, circuit diagrams, and complete code. This $35 DIY project replaces expensive commercial systems with ...

This can be mitigated somewhat by explicitly slowing down the speed of the SPI interface in the Arduino code, by including #define MFRC522_SPICLOCK (400000u) (Sets SPI bus to 400kHz) prior to ...

Arduino Code for RFID-based Authentication System. The code is developed using the Arduino IDE. The EM 18 RFID module operates on serial communication; when RFID is detected, it sends the data over ...

Inside is Arduino Pro Micro and a PMW 3389 optical sensor on a breakout board. [Ben] was going to use flexible 3D printed panels as mouse buttons, ...

Previously we interfaced MFRC522 RFID Module and EM-18 RFID Reader with Arduino. In this tutorial, we are going to interface RDM6300 RFID Reader Module with Arduino Nano. The RDM6300 RFID Reader is ...

"When transmitting, the M6e-Micro draws less current than is typical for a high-performance UHF RFID module. The module is able to consume as little as 0.025 Watts while remaining ready to react ...
