Arduino Communication: Basics of SPI Protocol

What is Arduino Communication: Basics of SPI Protocol?

Arduino Communication: Basics of SPI Protocol is a free online course offered by Alison US CA designed to teach the fundamentals of the Serial Peripheral Interface (SPI) protocol in the context of Arduino development. SPI, originally developed by Motorola in the 1970s, is a high-speed, full-duplex synchronous communication protocol used for short-distance, board-level communication between microcontrollers and peripheral devices like sensors, displays, and memory chips. This course breaks down complex concepts into accessible lessons, making it easier for learners to understand how data is transmitted and received simultaneously using SPI in real-world Arduino applications.
