+== Create a mote with Raspberry Pi
+
+The Raspberry Pi is a low-cost credit-card sized single-board computer. The Raspberry Pi was created in the UK by the Raspberry Pi Foundation. The Raspberry Pi Foundation's goal is to "advance the education of adults and children, particularly in the field of computers, computer science and related subjects."

+[NOTE]
+.Remember
+====
+A mote is a node but a node is not always a mote!

+
+====
+
+
+=== Install Raspberry Pi 
+
+==== Step 1: Download Raspbian
+
+https://www.raspberrypi.org/downloads/raspbian/[Download] the Raspbian disc image  - Choose Raspbian Lite
+
+[NOTE]
+.Why Raspbian Lite?
+====
+Because it is a lightweight version of the Raspbian and it doesn’t have a graphical user interface installed. 
+
+This means that it doesn’t have any unnecessary software installed that we don’t need for our  projects, so this makes it the perfect solution for future automation projects.
+====
+
+==== Step 2: Unzip the file
+
+
+- Windows users, you’ll want 7-Zip.
+- Linux users will use the appropriately named Unzip.
+
+
+==== Step 3: Write the disc image to your microSD card
+
+Next, pop your microSD card into your computer and write the disc image to it. You’ll need a specific program to do this:
+
+- Windows users, your answer is https://sourceforge.net/projects/win32diskimager/[Win32 Disk Imager].
+- Linux people, https://www.balena.io/etcher/[Etcher – which also works on Windows – is what the Raspberry Pi Foundation recommends.]
+
+The process of actually writing the image will be slightly different across these programs, but it’s pretty self-explanatory no matter what you’re using. 
+
+- Each of these programs will have you select the destination (make sure you’ve picked your microSD card!) and the disc image (the unzipped Raspbian file). 
+- Choose, double-check, and then hit the button to write.
+
+
+==== Step 4: Enabling SSH
+
+- Windows users
+
+.Create ssh file (no extension)
+image:./ssh-file-to-sd-card.jpg[alt="Create ssh file"]
+
+- Linux Users
+
+.sketch Create ssh file
+[source,bash]
+----
+sudo fdisk -l
+# find dev and Boot partition
+sudo mkdir /mnt/sdcardP1
+sudo mount /dev/device_partion_boot /mnt/sdcardP1 -rw
+cd /mnt/sdcardP1
+sudo touch ssh
+----
+
+==== Step 5: Put the microSD card in your Pi and boot up
+
+Your default credentials are username **pi** and password **raspberry**
+
+
+==== Step 6: Access via SSH
+
+
+-  The boot protocol for the ethernet interface is set to DHCP by default 
+
+You can find the open SSH ports on your network using the nmap utility:
+
+
+.find ports on Network
+[source,bash]
+----
+nmap -p 22 --open -sV 192.168.1.0/24
+----
+
+You should find your pi listed in the output along with the IP assigned to the pi.
+
+
+- You can change the boot protocol to static and define a static IP address for the pi by editing the ifcfg-eth0 file:
+
+.static IP address
+[source,bash]
+----
+sudo fdisk -l
+# find dev and Boot partition
+sudo mkdir /mnt/sdcardP1
+sudo mount /dev/device_partion_ext /mnt/sdcardP1 -rw
+cd /mnt/sdcardP1
+vi /etc/sysconfig/network-scripts/ifcfg-eth0 
+----
+
+Then edit the file to suit your needs
+
+.static IP address
+[source,bash]
+----
+DEVICE=eth0
+BOOTPROTO=static
+ONBOOT=yes
+NETWORK=192.168.1.0
+NETMASK=255.255.255.0
+IPADDR=192.168.1.200
+GATEWAY=192.168.1.1
+----
+
+
+==== Step 7: Configure your Raspberry Pi.
+
+**raspi-config** is the Raspberry Pi configuration tool 
+
+
+.config Pi
+[source,bash]
+----
+sudo raspi-config
+----
+
+It has the following options available:
+
+.config options
