This project is the simple interface between two microcontrollers and python. Project technology: Arduino - This is a microcontroller that support different communication protocols (UART,SPI, I2C) to ...

PlatformIO example project showing how to use RC522 Mini in i2c mode. To set the breakout board in i2c mode you need to cut the connection grounding pin 1 as discussed in this thread on the arduino ...

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.

[Sigurd] manage to obtain an old vending machine from his dorm. The only problem was that the micocontroller on the main board was broken. He and his friend decided they could most likely get the ...

Therefore, an effort was made to design a tool for “identification of impedance changes in metals using an Arduino Uno-based RFID RC522” which is relatively inexpensive and easy to carry.
