When using photoresistors with the MIDISense ADIO board is there a preferred way to hookup to the analog input connections AN1 through AN6?
On the schematic it shows pin 1 to be ground, pin 2 to be +5V and pin 3 to be Vcc.
So I have tried using the photocells going from pin 1 to pin 2 and this works but I find the photocells to have a limited response range visually as shown when doing the calibration. I have added fixed resistors across pin 2 and 3 and I find that I get a larger response range. Is this right?

but on the site of ladyada it says
"Use this with the resistive sensor board."
http://www.ladyada.net/make/midisense/environsensors.html
did you connect it to the ADIO sensor board ??
is that working good ?

dear soundtree, can you post a photo of your project?
because I tried to do it but it doesnt work.
thank you
