I would like to hook up multiple sensor of the same type (temperature, pressure and so on). The problem is that each sensor can only have 2 different unique values for the register, so can't put more than 2 on a single I2C bus.
I would like to multiplex the I2C channel; so I can plug more sensor; altho I do not know
What kind of breadboard to get (found few store online that has analog multiplexer; is that OK for my case?)
What kind of code should I write? Do I have to ping each sensor in a sequential way? is there an example about how to cycle trough various sensor using a multiplexer?
I use an Arduino clone board, called Teensy; but I saw also a nice clone called Trinket pro; they both are programmed via the Arduino programming language; so any example would be really appreciated.
