Power Supply Conditioning Question

Hi all,

I'm working on a project that integrates multiple sensors. I'd like to power each of the sensors from the Arduino's 5v and/or 3.3v power pins. The spec sheets for the sensors recommend power filtering caps (usually 1uF and .01uF). My question is, does each sensor need its own filter caps physically "close" to the component or can I get by with just placing the caps anywhere on the power bus? Thanks in advance!

critical problem… i am also facing this problem…

Such 'bypass' filter caps work best if wired right at the sensor chip. Also if using the on-board 3.3vdc power pin be aware that there is a maximum current draw of around 50ma as this 'regulator' is built inside of the FTDI serial USB converter chip and is not meant to provide very much current at all.
