On a roll but stuck in a rut (where's the beep?)

hey there,

I’ve been working on a Tri-Track with a Sabertooth 2x10 RC motor driver and so far everything is up and running as per the instructions. I should note that I’ve been using the Rover/PS2 instructions because I’m using the 2x10 not the 2x5 and my main goal is to use the PS2 as the controller.

I’m currently on step 7 ~ Differential or Tank Mode Test (Optional) and the A/B/C buttons and direction are correct but for some reason the bot board will not beep? I can almost 100% verify that I have all the jumpers placed in the correct order as per figure 5, also the program loaded successfully with no errors.

any help would be appreciated :wink:

I just tried setting the jumpers up as per figure 4 for the Tri-Track tutorial (figure 10 for the Rover) but still no luck.

So it’s up and running with the PS2 controller :smiley:
…but stil no beep :open_mouth:

The botboards buzzer thingy is connected to pin9, if something else uses pin 9, it wont work,

try adding this command
Sound P9,[60\3500,40\3000,20\2500]

when that command triggers it should make 3 different tone beeps in quick succession.

Thanks for the suggestion Fallentine but I’m not sure if I quite follow? the 3 programs I have loaded all had something similar to the line you offered.

On a another note, I took the jumper off the buzzer and added one to the 5v for pin 9 along with a bread boarded buzzer of my own and still did not get a beep.

I’m not sure i follow you.
You don’t need to add a jumper to get power to p9, you’ll most likely fry you chip by feeding power back into it.

The jumper next to the jumper is all you need, you leave #9’s signal/voltage/ground pins open.

you’ll notice i have a light blue jumper on near the buzzer.
It might be hard to see, but P9 is not connected to anything else.

The BAtom pro supplies the power to the buzzer automatically.

Thanks again Fallentine, just to be clear I didn’t add any jumpers ‘to’ pin 9, I only added jumpers (sig,ground,5v) ‘from’ pin 9 out to a bread board with a different buzzer to test it (I thought it would still send the signal to pin 9?), this is also after the fact and also after running the other programs with success except the beep.

I tried to remove/re-inserting the chip as well as adding the ALD 5 arm and everything works. The Lynxmotion controller flashes red then connects instantly and as far as I can see it runs as per the directions. Still no beep? I’m starting to think I just got a faulty Bot Board :frowning: or now I guess you can call it a BBB (Bunk Bot Board). :neutral_face:

Any other ideas would be appreciated.

So as my short term memory has it, I had ordered 2 Bot Boards with the second one being for a Hexapod I’d like to build one day and low and behold it works!

I set it up the same way as the first one and popped in the chip powered it up and it beeps looking for the controller. So I can officially say that the buzzer was dead on arrival. :unamused:

can someone(mods?) please contact me about this.

I have told Robot Shop in an email to replace your Bot Board II. Sorry for the trouble. :blush:

no problem at all, half the fun of building something is getting it to work :wink:

Robotshop asked me to check underneath the buzzer to see if there is a proper connection and by comparing the two Bot Boards with a magnifying glass I can say that the faulty one’s joints do look to “not as good” in comparison.

example:

  • the good one’s legs are standing out as far as the pin headers legs are.
    ~ the other one only has one leg that stands about half the height as the pin headers.

  • the good ones solder joints look shiny a bit bigger than the headers(wire difference?).
    ~ the other one has barley any wire sticking out but you can see where it was trimmed, the solder joint is not cone shaped in comparison to the good one.
    ~ the other leg has a grey solder blob that is not much bigger than the rest of the smaller “solder spots” around it. There’s nothing that can be identified that there’s any wire under it(ie. no shape or wire trim marks).

hope this helps, I tried taking a picture but my camera’s focus is not the greatest for something that close. Thanks for your support and quick response on this matter (you too Fallentine!).

cheers!
