As you saw in the previous chapter, Arduino Galileo IDE is very simple to use and by now, you should already know how to compile and upload your sketches to the board.
One interesting feature of this IDE is that it allows you to execute command-line operations in the Galileo's Linux shell. This way, it is possible to print useful information in the Galileo serial connection through the Linux shell, such as the board IP address, and in this particular use case, your CPU temperature.
In this chapter, we will create a bootable SD card, connect our board to the Internet using an Ethernet cable or Wi-Fi, read the Galileo CPU internal temperature sensor, and plot the collected data to an online chart.
In this chapter, we will cover the following topics:
Burning a Linux bootable image to an SD card
Booting Galileo from a microSD card
Connecting to the Internet using a wired or wireless...
