Hello pd forum,
I'm working on a multi-sensor project with Arduino running Standard Firmata to a pduino patch into Ableton. I've got the first sensor working fine (an infrared proximity sensor). But when I try to add another sensor to the mix I can't get it to work. I've tried doubling up sensor inputs on a breadboard running to same analog in pin and tried using a separate second analog input pin for second sensor but neither works. Any suggestions? I suspect the problem is with my pd patch. I've attached a screen shot of the single sensor patch that works. Help greatly appreciated. I am new to learning pd so this may be a simple problem.
This patch is a simplified version of pduino. I copied it from a tutorial which suggested the simplification. Perhaps this is the problem. The other weird thing is that although I am running the one sensor into analog input 2 on the Arduino it doesn't work unless pin 4 is enabled for analog input too, even though there is nothing physically connected to that input on the Arduino. Any explanations for that?
Thanks in advance for any help.

Can't see any screen shot...it would help.
