Halloween Is Coming Soon

Skip to comments   Jump to end

Hello To All,

This time of year my old plc controllers and arduino ends up at my friends Halloween Barn. I program a number of displays for our friends, both fiends and ghouls amusement.

This year my poor robots will become brainless for a while and two of my ezbv4's will become an addition to the party. One may run a talking head with facial tracking.

I was wondering if the object tracking mode works with an IR camera hooked to my computer? I would like to use my second ezb to run servos and a couple relays using object location and tracking (people) in the dark.

Any experiences or ideas?

Upgrade to ARC Pro

Harnessing the power of ARC Pro, your robot can be more than just a simple automated machine.

Yes, any camera recognized by windows should be able to work in ARC.

#2  

I hope it works. I assume I will have to set the contrast settings full to make it track. I will post my tests.

Hello to All,

My Madame Ninndo, the fortune teller is progressing well. I will post pictures soon.

I have built a number of Auto Position actions. I listed them in the script manager. I can run each of them by clicking the corresponding start button in the manager. Works well !

I want to activate the action by pressing a push button. Upon completion I also want to have the next action to be ready to run. Sort of like a sequencer. (FIFO) Upon the pressing of the button again, the next action will run, and upon completion advance to ready the next one. Can someone help?

I planned on using a standard push button on a digital input to be the signal. Do I need to build an anti-bounce circuit?

My scripting skills are minimal, but I want to learn.

Thanks,

Monitor the digital port with the push button on it. If it's on D0 for example


WaitUntil(d0 = true)

NB: I haven't used EZ-Script for over 6 months so my commands may be rusty, I'm unable to find the EZ-Script manual online so can't confirm WaitUntil() is a valid command or the syntax is correct.

Have a counter which increments so you can cycle through actions.


$counter = 0

Increment it each time the button is pushed


$counter++

Run the required script dependant on the counter


IF($counter = 1)
  ControlCommand...
ElseIF($counter = 2)
  ControlCommand...
...

Build in some kind of loop to avoid the counter going over the number of actions at the end of the if nest


...
ElseIF($counter > 10)
  $counter = 0
EndIF

Thanks Rich, I will give it a try.

Hi Rich,

I wasn't able to get the script you gave me to work. I understand how it flows but must be missing something. I am trying to get some thing easy to work to learn the basics, but I am missing something.

I tried the following to confirm the input script is ok, but it doesn't work. I must not have the right code.

If (d0= true)

Sleep(500)

Say ("EZB is on") Sleep (500)

Endif

)I also tried it without the Sleep commands)

I tried WaitUntil (d0=true) but no good.

I put a digital read block to see if the input works and it does.

Do you know of any working examples anywhere ? The sequencer is the last part needed for this project, and I want to get it working by Wednesday.

Thanks

Ron you should use the UBB code when posting things like code snippets... Try this... It waits for a digital change then executes the "if" condition...


:top
# Digital_Wait(D0, ON, 50) waits 50ms for digital change
WaitForChange(GetDigital(D0))
If(GetDigital(D0)=1) #true
Sleep(500)

Say ("EZB is on")
Sleep (500)

else #false
#do something else
endif
goto(top)

Hello Richard R,

Thanks, I will try the code.

My next step is a sequencer. This script is just to check to be sure the input works and doesn't bounce thus skipping steps.
