To install the software, you’ll need to connect a USB
keyboard, HDMI monitor, and an Ethernet cable to the
RaspPi ports as shown in Figure 6.
You will also need an 8 GB or larger micro SD card to
put the OS and program on.
The following steps walk you through the install
process at a high level. You may have to tweak some of
the steps as the OS changes over time and menu options
get moved around and renamed.
Google is your friend. If you get stuck, do some
searching. There is an unbelievable amount of information
on the Web about the Pi.
Software Setup (note the first two steps are done from a
Windows 7 or Windows 10 PC):
1. Download the latest version of Raspbian Jessie from the
Raspberry Pi Downloads tab at https://downloads.
raspberrypi.org/raspbian_lite_latest to your Windows PC.
2. Open Win32 Disk Imager and write your image to a
fresh SD card. Everything will fit on an 8 GB card. If you
don’t have Win32 Disk Imager, you can search for
“Win32DiskImager” and download it for Windows. (You’ll
need a way to plug in the SD card to your Windows PC.
There are several USB SD card readers available on
Amazon if your PC doesn’t have it built in.)
3. Take your SD card out of your Windows PC and put it
into your Pi. Connect a USB keyboard and HDMI monitor
as shown in Figure 6. Boot the weather gauge up and log
