1.3.1 Installation IDE
AduinoIDE is an open source software and hardware tool written by open source software such as Java,
Processing, and avr-gcc. It is an integrated development environment that runs on a computer. It can write
and transfer programs to the board. The major feature of the IDE is cross-platform compatibility for
Windows, MaxOSX, and Linux. Only a simple code base is needed, and the creators can create personalized
home internet solutions through the platform, such as remote home monitoring and constant temperature
control and so on.
In this tutorial, we use the version is 1.8.9, download address is :
