61 | Connecting to the Outside WorldConnecting to the Outside WorldNote: At the time of this guide’s publication, it was not possible for the following three projects to becarried out using the NSW DEC network as there were not sufficient ports open for communication.Sending Email from your GalileoOverviewThis activity sends an email from your Galileo when you run the program. It makes use of theSimple Mail Transfer Protocol (SMTP) to send the email. The SMTP protocol is the protocol usedby the majority of all mails that are transferred around the internet. Here are a couple of linksabout how SMTP works:http://www.ballisticdomains.com/articles/art-web-hosting/138-smtp-servershttp://www.laynetworks.com/smtp.htmMaterials»»1 x Intel® Galileo Gen 2 board»»1 x 12V Power supply»»1 x Micro USB leadCoding1. Connect up to your Galileo using Putty or Terminal.2. From the Linux console, using the vi editor, copy and paste the following code into a filecalled SendEmailOnButtonPress.py3. Run the program from the command prompt by typing in:4. root@clanton~# python SendEmailOnButtonPress.py5. Press the button and an email should be sent.import smtplibFROM='SarahsGalileo@gmail.com' # can be a fake email addressTO=[recipient1@email.com, recipient2@email.com,]SUBJECT="I am alive"TEXT="This is from the Galileo"#Prepare actual messagemessage = """\From: %sTo: %sSubject: %s%s
