Steve G · Answer

Not bad @nomad, not bad at all. Fairly simple, but very effective and looks great. Nice thinking and good job.

Nomad 6R · Answer

i got the tip from rich .next time use a brigher led.

bborastero · Answer

that's cool and so simple, it took me a while to find something to flash an LED to sound, I followed this thread https://synthiam.com/Community/Questions/7173 and also found this code I can't remember where
$Soundv4Value = 100 :loop waitforchange($Soundv4Value) PWM(D10,$Soundv4Value) goto(loop)

both work but yours is so easy (EZ)

thetechguru · Answer

@bborastero, The advantage of the script and a digital port is that you can turn it on and off based on whether the robot is speaking or playing music, but Nomad's solution has a simple elegance and avoids all of the issue with the soundservo control. (I find using the script with sound servo it goes out of sync with longer sentences). Alan

Nomad 6R · Answer

bborastero i can use yours too.

Nomad 6R · Answer

so where do you connect the led?on a digital or anoloog port?

thetechguru · Answer

Quote:so where do you connect the led?on a digital or analog port? On a digital port. Then, if using the script bborastero posted, you need a Sound Server V4 object, but you don't need to configure it to a servo (it is just to populate the variable used in the script), then create the script and start it. The LED will blink whenever the EZ-B makes sound and the script is running, and it varies in brightness based on the volume. That example used port D10, but you can use others, just modify the PWM statement as needed. Alan

thanks alan

nomad, Great work and independent thinking! Maybe it will be on the next JD? Steve S

thanks steve S

@nomad... Just a reminder the white digital pin can only supply about 20mA... so just be careful what to attach to that pin as anything more than 20mA can damage the port...

Nomad 6R · Answer

rr for leds i use only black/red

Dunning-Kruger · Answer

@nomad... maybe, but without the digital pin you can control them... PWM is on the digital pin (white) not the red pin. If you are going to use @bborastero's script you will need to use the digital pin not the power pin...

@thetechguru Quote: (I find using the script with sound servo it goes out of sync with longer sentences). agreed I've noticed the same thing. still I like the hard wire choice too.

Nomad 6R · Answer

rr ah.thanks for telling. so i use black/white and sound servo to get same or better result?

thetechguru · Answer

The results will be about the same. Only advantage of the script and sound servo are that you can turn it off if you want to make other sounds without the mouth blinking. I think your solution may actually work better. Alan

Nomad 6R · Answer

oh really ? thanks for telling alan

Nomad 6R · Answer

i changed the mouth led cause it was not chowing up like i wanted. i didn had brighter led but what i got is MP3 volumer. i dont remembet who gave me the tip,sorry for that. so it makes the mp3 file louder and also makes the led chine much better. in the video you see bolt.the older mp3 files and the new ones.

Dunning-Kruger · Answer

@Nomad.... Good job Patrick..... I like how it completely syncs to speech... no delay...

Nomad 6R · Answer

thanks avery one yes and its better to see. am almost reddy whit another surprise.hehe

Steve G · Answer

@nomad. The LED change looks so much better. Well done.

Nomad 6R · Answer

steve G glad you like it thank you

Tony1952 · Answer

That looks and sounds fantastic @nomad18.08 ! How did you form the oval shaped mouth in JD's head?

Nomad 6R · Answer

hi tony its actully round.

Tony1952 · Answer

hi @nomad18.08 so you just drilled a hole? Do you have a small resistor wired into the red line?

Nomad 6R · Answer

hi tony yes inside the ezb. pics

Tony1952 · Answer

Thanks @nomad18.08 Would it be a 1K ohm resistor?

Nomad 6R · Answer

hi tony. i make a pic cause i dont have knowledge about these things.

Nomad 6R · Answer

here is the pic

Tony1952 · Answer

Thanks @nomad18.08 ! Now I see how you got the neat black trim around the mouth

Nomad 6R · Answer

it clicks together and the led stays in place. the little ring has two sides.one side start the treath in the begin off the ring for , thinner plates.the other side start a little further for thiker plates. i melt the hole whit a little iron screwdriver and then whit a little round vijl, make it bigger.

Tony1952 · Answer

@nomad18.08 you have come up with a simple and excellent solution! Did you get that LED locally or off ebay? I can't find one like that anywhere

Nomad 6R · Answer

hi tony i by them from conrad.be or conrad.nl make sure you test a led whit the resistor on if its bright enough.

Tony1952 · Answer

Thanks @nomad18.08 I'll have a look!

Tony1952 · Answer

Sorry to bother you again @nomad18.08 I have searched through the massive conrad store but cannot find the LED you have shown in your picture on the previous page There are plenty of LEDs without the black socket (as per attached pic) Is the socket a separate item? Do you remember the name of it?

Nomad 6R · Answer

tony i will look it up see if i can find it back.

Nomad 6R · Answer

tony here some links led fitting led  maybe someone can chime in for howmany mcd tony will need. tony you find alot on ebay.us

Tony1952 · Answer

Many thanks for your help @nomad18.08 ! Yes, they are very cheap on ebay!

Nomad 6R · Answer

i checked my oreders from that year.i see two leds. one 200 mcd and one 4000mcd. i cant remember whits one i used. here a link all kinds off resistors. resistors
