Sending automated e-mails
In this last part of the chapter, we are going to build on what we already did, but change the
application slightly. This time, we are going to use the Ethernet shield and Temboo to auto-
matically send e-mails when a condition is reached. As an example, we will set a condition
on the measured temperature. Whenever the temperature reaches a given value, we will
send an e-mail to the address of your choice, for example, your professional e-mail to keep
you updated when you are at work.
It starts by going again to the Device Coder on the Temboo website at
ht-
Click on
Generic sensor
and then on
Email
. This time you won't have to enter that much
information. Your Gmail account should already be set from the previous section and the
Device Coder should automatically select your Ethernet shield.
You simply need to enter the destination e-mail (for example, your professional e-mail ad-
dress or the e-mail address from a family member) and the
Subject
field of the e-mail. Do
not worry now about the value of the body of the e-mail; we will change it later:
When it is finished, click on
Generate
. As for the previous section, you will be prompted
to enter a name for this project so that Temboo knows where to send e-mails. I named mine
arduinoTemperatureEmail
, but if you decide to use another name, you will simply
have to change one line in the code later.
You can now download the generated code, which we will modify a bit. As for the previous
section, we are going to modify the Arduino code, but it is important that you get your own
TembooAcccount.h
file that contains the information relative to your own account on
Temboo.
