Raspberry Pi and Temperature Sensors

I just got 2 temperature sensors from Adafruit.

• BMP180
• MCP9808

Here are mine after I soldered the headers on and wired them up on bread board.

They were very easy to use and didn't take much coding to get them up and running. They are both I2C and I was able to use my existing libraries to talk to them from the PI. I did put up code on github to show how to retrieve the temperature from both. The BMP180 has a few more things (ie. pressure, altitude, etc.) Though, the altitude wasn't very accurate to where I am. I am not sure about the pressure as I am not familiar with that... Either way, a fun project to get up and running!

Raspberry Pi GPIO with RGB LED

I was playing around more with the wiringPi library and a Red Green Blue LED. I have a simple setup that will blink the led in each color. From the video, it's a bit tough to distinguish between blue and green so I included a few pictures of each color as well.
