Getting Started with Arduino: Let’s Start with Hello World!
Let Arduino Say "Hello World"First, let's practice a simple experiment that requires no additional components, just an Arduino board and a download cable, to let our Arduino say "Hello World!" This is an experiment to communicate between Arduino and PC, and it's also a beginner's trial, hoping to lead everyone into the world of Arduino.Electronic Components and Modules Used in the Experiment:1 Arduino board: Any type of Arduino such as Uno/Mini/Nano, 2560 will work.USB data cable: I am using an Uno board here, which generally requires a Type B USB data cable.Here is a bit of knowledge about USB interfaces:Additionally, the board's driver must be correctly installed. Most domestic USB to serial converters use the CH340 chip, so the CH340
