Hi. First off, this is my first post. I got my Netduino Plus 2 a few days ago, and have been playing non stop. I currently have some analog sensors on it (Light and Temp+Humid) One of the projects I want to build will need an array of light sensors. (10 sensors in total, posibally 12) I am looking at the MAXIM MAX44009 light sensor. It uses I2C for comms, and has a very good light range.  My question is, on my ND 2+ I only have one I2C bus correct? And the MAX44009 sensor only has 2 possible addresses. So would I only be able to connect two of these sensors to my board? I have read up on I2C some, but I am still a little unsure if this would be the case. If this is so, are there any good I2C expander cards that I can attach to my board to allow me to connect more of the sensors? Also, has anyone ever used the MAX44009? Does it work well? Thanks so much for any info. Have a good day. Quintin
