Using SPI Protocol in Arduino. Before start programming for SPI communication between two Arduinos.We need to learn about the Arduino SPI library used in Arduino IDE.. The library <SPI.h> is included ...

SPI transactions became officially part of Arduino SPI library some time ago. This happened after many months (most of 2014) of lengthy discussion and testing for these and MANY other details.

While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI bus.

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. This ...
