Internet of Things (IoT) Thanksgiving Special: Turkey Tweeter (Part 2)

By now you should have received your Vernier Go!Temp USB Temperature Probe and it is getting really close now to Turkey Day, so you want kick your Internet of Things (IoT) Turkey Tweeter project into high gear now.

First, we need to test the temperature probe before sticking it into unknown places, namely our delicious IoT bird on Thanksgiving. So, take your Go!Temp USB temperature probe and plug it into your Raspberry Pi device, just like in this photo.

See:

Connect Go!Temp Probe

If all went well on your Raspberry Pi, you should be able to bring up a terminal shell connected to your RPi and type "lsusb" to verify that the Go!Temp probe is now connected.

pi@raspberrypi ~ $ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 005: ID 08f7:0002 Vernier EasyTemp/Go!Temp

If your output looks like above, especially the last line where it says the Vernier Go!Temp was recognized and is connected as Device 005, you are golden.

One last check before we start to program using a Java SE Embedded app to grab the temperature readings is to make sure the /dev/ldusb0 device is present. So, type this command and make sure your output matches:

pi@raspberrypi ~ $ ls -l /dev/ldusb0
crw------T 1 root root 180, 176 Nov 18 17:25 /dev/ldusb0

If all that looks good, you're ready for the next step which is to write a Java SE Embedded app to read the temperature values, and eventually write code with IoT intelligence to tweet out the status of your turkey while it's cooking so that it becomes an Internet of Things connected bird on Twitter. Look for that in the next part of this series... Mmmmm... I can almost smell that turkey roasting... :-)
