I came across the Speaker Tone feature and thought that was a very simple and neat way to add a bit-o-character without added expense. So I modded the plug on a piezo PC speaker an away I go...
But what I actually get sounds distorted and drawn out, like the note is being broken in little segments and extended (best way I can describe it). The volume is also very low.
I have tried and tested the following...
Latest firmware & good power - included battery pack and auxiliary 12v DC
Different speakers - voice coil (8ohm) and piezo... no difference at all.
Correct pins on ports (inner and outer GND and SIG) even reversed leads to speaker just in case... no diff. (and yes, I am using the digital ports... it is working, just distorted and quiet)
Tested multiple ports... no diff.
Tested with and without other items attached... no diff.
It is such a simple thing... not sure what I am possibly doing wrong... even followed the tutorial exactly (RTFM
) well, up to the scrip part... because what is on the video looks different then what I have on my ver. EZ-B. Darn upgrades
Is this an obsolete feature and I just missed the memo? I have scoured the forums to no avail.

Discovered the same problem last weekend Gunner but did not have the time to stick around to find a solution....
I, like you, will await for the guru's to speak!
The speaker tone I noticed went very low frequency a few releases ago I beleive DJ said it was due to processor time available in the EZ-B board?
I wasn't that bothered as I was doing other things at the time but it was quite good fun to have my Omnibot make R2D2 type sounds
Another thing I noticed but haven't had time to investigate further was the sound servo control that didn't seem to actually move an assigned servo there's too many other new goodies to play with each release. Perhaps someone else can confirm this?
I have also detected that tone speaker at low frequency, but only sometimes, when he opened several ping or overloaded long sensors screen with many controls, but that was some time ago, and many new versions have come from ARC. Is thought speed bluetoot could not work with all at once. Regarding the servo sound works for me very well, but more data here: RSP link
R2D2 thanks for the heads up on the sound servo (lol) I will try again tonight
Great video and Robot BTW
Oh! I didn't know there was a problem with the speaker tone. I used it on this release not too long ago for Omnibot - I'll have to check again and see
I had debated on removing this feature - not sure if it's that useful. Free up some memory for some more magic.
For me you can remove it. Its great fun to play with when you are new to EZ-B though
For me it is like the passenger side sun-visor mirror, fun to check out at first, but probably ignored from then on... but when you later need it, it is nice to have
I'll just wait and see what DJ chooses... unfortunately an MP3 sound board is low on my budget priority... but hey, I can move servos and stuff!
Sorry R2D2
Well I can't get the sound servo control to work. I get the graphs and can adjust the scalar etc and the control indicates the servo position changing when the PC's mic detects sounds but when I assign a servo the servo position indicator then doesn't change
I declare it broken I'm sure its a small fix though
