esp32 spi communication tutorial with Arduino IDE

In this tutorial, we will learn to use SPI communication buses of ESP32. By using that, we will see how to perform master slave SPI communication with ESP32 boards using Arduino IDE. Furthermore, we will look into SPI pins, how to use multiple SPI bus interfaces supported by ESP32, and how to configure them. Recommended … Read more

SPI Communication Between Two Arduino Boards

October 9, 2026

In this tutorial, you will learn to use SPI communication port of Arduino. As an example, we will demonstrate SPI communication between two Arduino boards. It is a 4-wired serial communication protocol. It supports single master and multi slave communication. Therefore, in this tutorial, we will configure one Arduino as a master device and other board … Read more
