Select the script code, press CTRL and C together to copy it, and paste it on the forum thread inbetween the "Code" tags.

ctrl+c and press copie to clipboard? paste is ctrl+v ?

@Nomad Open your script in ARC, highlight it all with your mouse, copy it... then come here and paste it into your post.... done

@Nomad you can also just give us a screen shot of your script...

You can also copy and paste by right clicking on your mouse

@Richard.

I've never been able to copy or paste script to and from ARC using a mouse or trackpad.

@Steve Hmmm, that's weird... You're right... I pretty much use ctrl + C, V, X exclusively so I had never noticed right clicking doesn't work in ARC scripts

Shouldn't there be an "If" and "EndIf" code in there, like "if ping is lower than 50, do or say this"?

@nomad.

See what you gone and did... You went and broke the EZ Robot website, lol. :P

Anyway back to your problem. Try this...

:loop
Ping_wait(D21,D22,Lower,50)
Servo(D3,90)
SayEZB("Danger, danger, danger")
Sleep(3000)
Goto(loop)

When you start the script the Ping sensor will start detecting distance. Now when the value goes below 50, the EZ-B will say Danger. It will sleep for three seconds and start start detecting distance again.

Hope it helps.

hi guys

sorry late respons.i couldn get on the forum here.

rr

yes the ping works at port D22 AND D22 but not the script thanks averyone

#21  

@nomad... Just after the site went down I remembered there is a bug that DJ knows about... Some ping commands (haven't checked all of them) do not work on ports 23 and 22... As DJ mentioned, you need you use ports 21 or lower...

@nomad.

If my script doesn't work for you (it does work as I tested it) then it maybe what Richard said about using port 22.

do i need to ad in the script for more volume

#27  

You can setvolume(1xx) higher than 100, but it will begin to distort the higher you go as it will basically be overdrive above 100

@nomad.

Good to see it working. I won't give you the script to do what you asked, but I'll give you some clues to what you need so you can Give it a try.

If the ping sensor reads over 50, play sonar sound and rotate the servo.

or else if ping sensor reads below 50, stop sonar sound effect and say "danger".

Put in a sleep command.

Go to the start of the script and do the process again.

The clues of what script commands you need are written above. Give it a try and report back.

Good luck.

#35  

@nomad.

No problem. Truth be told, I'm not 100% sure how to write the script as im still learning too, but I understand the principles and what's needed...

If over 50, scan and play sonar sound

Elseif under 50, stop scan and sonar sound and say "Danger".

If I had my laptop with me I could probably write the script okay, but I'm away for the weekend so can't give you more than that for now.

@Richard.

That's a new one for me. I haven't come across that before.

Steve, :Top is a label for the Goto command

Goto will "jump" to the label

A script starts from the top and reads each line downward

When the line reads GOTO(label), then the script will jump to the label. In this case, the label is called TOP. You can name the label anything you want.

You can name the label CHICKEN, if you like chickens. Or you can name it something that identifies what it is for, in which case CHICKEN wouldn't make sense.

Richard used TOP because it's the top of the script. He could have named it anything, but it's nice to name it something that us humans can understand when reading the code back.

For more information, load the GOTO RETURN STACK.EZB project located in Examples\EZ-Script Function Syntax folder

#41  

@DJ.

That's cool. I guessed it was a GOTO but didn't realise you could rename, or should I say label it with a custom named. I'll have a look at the examples folder.

Thanks.

United Kingdom
#45  

@nomad.

From how I understanding now, that's not correct. In your example, :loop doesn't go above :chicken, :loop is :chicken (or :whatever you name it).

Quote from the script manual...

Defines a label for a GOTO() command Example: :My_Label [/quote]

@RichardR a little off topic but I've always wondered why you use the impossible statement in a repeatuntil rather than a label/goto loop?

PRO
Synthiam
#49  

Is the RepeatUntil() what Richard uses to exit a script?

You can exit a script with HALT()

#50  

@Rich For obvious reasons I use an impossible statement to have the repeatuntil loop repeat forever... When I first stated using ez robot about a year and a half ago, I did use goto loops instead of repeatuntil... However, it might be just with the ezb3 (because this is what I was using) after a minute or two in a goto loop the ping would fail to fire. With a sleep set at 100 between checks, the ping would just stop working for some reason... I replaced my "read ping goto loops" with a repeatuntil loops and it immediately fixed the ping/firing problem...

To be honest I feel the repeatuntil statement is just a better way to do infinite loops. Goto statements are more meant to jump from place to place in your code...

#51  

@nomad.... Try this and let me know if it does what you want... I had to fix my if statement... forgot the brackets...

rr goodmorning

danger danger danger is track-4 actully sonar is track-5

it did nothing just lot off heavy noise this is what i want to have.

first ping goes left and right whithout detect any and play sound file (sonar)

then when he spot something stand still and play danger danger danger. when the object leaves he goes back to left and right whit sonar sound.

rr the previous one stops rotating and disconnects the ezbv4

#56  

Which script? What post #?

How long are those sound files 4 and 5 when you play them on their own? 1,2 or more seconds long?

Take out the ControlCommand("Soundboard v4", Stop commands and see if it still disconnects... Make sure you battery is good as well... a weak battery would cause your ezb to disconnect while moving or attempting to move servos...

rr i just try post #55 and post #53 bolt doesn move the servo and disconnect the ezbv4

#58  

batt are fully charged

sound files are 4 seconds each. took the command stop out. last little longer but disconnect ezbv4

#59  

It works for fine for me albeit I am using different sound files and a fresh battery...

You'll to write your own then because I don't know your set up so that's the best I can do... Like I said... check your battery

One last try... see if this works ... problem will be it will only play track 5 once until it sees an object...

#you may need a sleep command here.i put one in and it doesn disconnect the, ezbv4.ok i will test further.thank you

#62  

Ok, work with that one then... the one I just in posted in post #61 probably will work, but it won't play track 5 continually...

#63  

@Nomad maybe a possible feature request is to be able to have tracks in the soundboard auto replay so you don't have the call it to play continually in a program repeatuntil or goto loop...... In your case track 5 is only 4 seconds long so having it auto replay would make what you want to do much easier... So this way you start track 5 (ping sound) and it plays over and over until you see an object that is detected with the ping ... Then track 4 plays... When the object is no longer in range your program starts track 5 again...
