I had a little bit of trouble tracking down the datasheet for some PIR sensors I bought recently, but finally found a good link:
It looks like I can adjust both the time delay as well as the sensitivity on these; can’t wait to hook a few of these up to an Azure Event Hub!
Below are some useful reference materials for working with Raspberry PI:
I received a new Raspberry PI 2 and fired it up today. Upon running my first GPIO enabled program I got the following error:
“This module can only be run on a Raspberry Pi!”
To resolve, I just needed to update RPI.GPIO:
sudo apt-get update && sudo apt-get install python-rpi.gpio python3-rpi.gpio

I love my Bose Companion 5 speakers, but had a bit of trouble getting them to work on a Toshiba Portege I recently rebuilt with Ubuntu. Here are the steps to get it working:
- Plug the speakers into a USB port
- Go to sound settings, the speakers should now appear. Select them.
- Open terminal and run sudo gedit /etc/modprobe.d/alsa-base.conf
- Change last line that reads: options snd-usb-audio index=-2 to options snd-usb-audio index=-1
- In terminal run alsamixer
- Select the Bose sound card (F6)
- Use the arrow keys to increase the volume
- Fire up Pandora and rock out!
