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 ...

In this tutorial we will use I2C communication between two arduino boards and send (0 to 127) values to each other by using potentiometer.

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [… ...
