  • I love my FIO, but I'm constantly wishing there was a version that could supply the 5V that a lot of sensors demand.

  • Would this still function properly if supplied with just 3.3v?

  • I'm working with a Arduino Fio and only have 3.3v available. I tried scaling down the resistors keeping current constant, but the values coming out are erratic. With no interaction, the output oscillates between 0 and ~90 over a 2 - 3 second cycle. If I wave an object infront of it, the values occasionally respond by jumping to 150-200 for a half second but return to the oscillating pattern. I'm an ME not an EE :( Can anyone shed some light on what might be going on and how to accomodate the low source voltage?

No public wish lists :(
