If i had an accelerometer connected to vcc, gnd, a1, a2, a3, I can get the readings from the accelerometer with a simple analog read. But this is my question, if i have a different sensor connected to a1 while the accelerometers still connected can i get the reading from the other sensor if the accelerometers vcc isn't connected?
Richard is correct, but if you NEED to have 2 sensors on the same pins you can use a analog multiplexer which acts similar to a multiposition switch and scroll through the inputs as fast as needed
IF the accelerometer goes into a high-impedance (3-state) condition when power is removed,
It dosn't.
and IF whatever the other analog source(s) is low-impedance enough so that the accelerometer doesn't interfere with its signal.
If this were the case then the sensor would override the accelerometer even when it was active.
So to the origional poster - forget it no.
Yes, I didnt a test last night and it did not work. I've decided to go with a hp4067 surface mount 16 channel multiplexer, so I'll get 16 analog pins for the price of 5 digital pins.
Thanks again for all the help.
