Using SRF005 with arduino

Can anyone please show me how to program my arduino duemilanove  to use the SRF005 ultrasound? 

thanks in advance : )

picaxe and l293d

if i got this right using a picaxe 28x1 project board (http://www.rev-ed.co.uk/docs/AXE020.pdf) and a l293d motor controller i can control  only 2 motors. For my robot i will need to control 6 motors. What can i do? is there a way to connect more than one l293d to my project board? (all motors must be able to move both directions) 

ultrasound interference

Another question. Am planning to use 3 ultrasound one directly above the other at about 3 cm distance from each other my question is there a possibilitty that their signals interfere with each other thus messing out the results?

controll phidget with picaxe

Can i use phidget sensors using a picaxe 28x1 and a picaxe poject board?

What microcontroller should i use?

Am planning on building a robot that  would have the abilitty to navigate , avoid obstacles and collect some items.

What chip should i use?

Whats the difference between pic and picAxE?


thanks in advance :)
