A simple If () statement will do the instruction trick. Of course, you can compile code for Arduino to continuously echo "Hello World!" without instruction. In this project, you only need an Arduino and a USB cable to start the "Hello World!" experiment. This is a communication test of your Arduino and PC, also a primer project for you to have your first try of the Arduino world!Īfter installing driver for Arduino, let's open Arduino software and compile code that enables Arduino to print "Hello World!" under your instruction.
#Uno r3 software serial#
Select the Serial Port used by the boardĪs for starters, we will begin with something simple.
#Uno r3 software install#
Install the drivers (If the computer does not automatically download and install the necessary USB drivers, point the hardware setup to the "drivers" directory of the Arduino IDE application.)Ħ. Connect the UNO R3 board to one of your computer's USB port.ģ. Download the Arduino Environment (IDE) and install or unzip/extract the application directory.Ģ.
#Uno r3 software mac os#
Click on the link for Windows, Mac OS X, or Linux for more specific directions.ġ. Click Learning, and select Getting started. As you install libraries for additional shields, new examples may be available.įollow the getting started guide found on the web site. The latest Arduino Integrated Development Environment (IDE) necessary for programming your UNO R3 board can be obtained at (the Download menu choice on )Įxamples for many basic components can be found under the Examples menu. Core functions, code examples, and links to many of the device libraries can be found in the learning section refer to the manufacturer's site if using other add-on shields or sensors. See for detailed specifications, overviews, schematics, etc.
