How do you save data from an Arduino-based device to a memory card? Fortunately, a microSD card and SD card breakout board now make this an easy task. Below is a simple tutorial on how to capture data ...

This is a board that connects the RC522 board with an Arduino Nano. This project was made out of frustration due to wiring the RC522 board with an Arduino Nano every time I wanted to use it. The RC522 ...

A few days ago, one of [Severin]’s SD cards died on him, Instead of trashing the card, he decided to investigate what was actually wrong with the card and ended up recovering most of the data using an ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

RFID Module: Reads the UID from an RFID tag/card. If the UID matches the authorized UID, access is granted. This project is open-source and can be freely used for educational purposes. I demonstrate ...

[Kevin] has been working on reverse engineering the protocol used by the Arduino IDE and porting it to the Arduino platform. Now that his BootDrive project is nearing completion, he’s ready to give ...
