Establishing SPI Communication between Arduino Uno and Nano: A Step-by-Step Guide
Introduction: Serial Peripheral Interface (SPI) is a widely used communication protocol in embedded systems, particularly in microcontrollers like Arduino. SPI is a synchronous, full-duplex protocol that allows multiple devices to communicate with each other using a common set of pins. In this setup, the SS (Slave Select) pin is used to select which device the […]
