Hello.
I am intending to use a total of 19 servo's in my robot. 1 servo to sweep the Ultrasonic pic sensor, and the other 18 servo's for the legs and movement of the robot. Ive read in the tutorial for connecting the ping sensor, that I will need to hook it up to 2 I/O ports. But with 19 servo's connected on the board, I would only have 1 digital port left.
I notice those 8 additional analog ports on the board, is it possible to use those analog ports and connect servo's or sensors to those? I was thinking of maybe adding a speaker or some leds if possible. Can those analog ports be used for such things too?
Thanks, Kristian.
Great. I'm curious to see what DJ finds out.
Thats interesting, thanks. I have read the manual but couldn't really get an idea what they are used for. I'll read into the tutorial section more.

Yeah, the manual is pretty light, and really just covers the hardware. The tutorials and videos are how you really learn what the board can do (and the forum posts and release notes posted there).

Thanks! They have loads of things, very nice! I will be ordering there for sure.

Is there any news on tie-ing the trigger and echo wires of the Ultrasonic sensor together for use with 1 I/O port?

Seeedstudio has the exact same 1 line ping)) sensor, but a lot cheaper! I have it and it works perfectly with the ez-b!

@okidey there is a way to use trigger and echo tied together,you need a transistor to ping the sensor and thenn it receives,need to add a delay in sending digital output and receiving one
