Last Questions

i start a new topic cause i dont want to ruing the great topic off the b9.

few questions.i have these resistors here,but there are no labels i cant read.so i post a pic.
also i have a link off 330 ohm reesistors.and my last question will be.does anyone has,
the size off the backside servo/foot till the end off the foot.

thank you all for this masive support.

As Richard said, set it to DC 20v (top left). I believe the red probe needs to plug in to the red socket on the multimeter, I am not sure what the yellow one (which you pointed an arrow to) does. It should say in the manual for the meter, since all meters are different it's hard to be sure (my meter only has 2 sockets)

ah .the red arrow pointed to socket whit name DC

@Rich that's the setting (yellow plug) to read amps (up to 10amps) that a device may be using... Most of these meter's are not fused on this setting, so use it cautiously.... And yes, plug it into the red socket for all settings except if you're using the 10amp to check a devices draw...

Try it on a battery.

Set the dial to DV 20v (as you showed above)
Connect the red probe to the red socket and to the positive terminal of the battery
Connect the black probe to the black socket and to the negative terminal of the battery
The meter should display the battery voltage.

Note: Make sure the battery is rated at 20v or less. I would test on an AA battery which should show 1.2-1.5v

yes i know how these works,also i know how to use the ohm.
so 1 off the holes chould read positif,there i solder the resistor on.
the hole thats left the negatif.

can you see in begin this topic is a link off resistor 330 if thats a good one.

Here's a quick schematic for you based from Jeremie's suggestion.

ah haha
i was thinking,whats he doing?thank you for the tip.

say moviemaker is this link the wright led i need for this topic?

LED 330

@nomad18.08... Are you looking for a basic 330Ohm resistor or are you looking for an LED?
United Kingdom

Any 1/4 watt 330 ohm resistor will do, it should have the coloured bands Orange Orange Brown. If buying online it will just be a case of searching for 330 ohm.

As for LED, any red LED should do.

You will probably find it's cheaper to buy in bulk than to buy 1 resistor and 1 LED.

If it wasn't for the stupidly high postage charges I would send you a 330 ohm resistor and LED but the cost of shipping makes it cheaper to buy them from your country.

hi

yes the chipping cost is mostly rediculous high.
i bouth some time ago a bulk leds.and some beginners resistors.
also i need some pink leds to.

thank you

You will not be able to run much off of the spkr connections, the current there will be very low hence why Jeremie suggested only red LEDs (since these take less current).

I would still consider using the Sound servo control and a digital port to trigger the LEDs without modification to the EZ-B though, this way would also mean you could power more than a single red LED, in fact it opens up a whole lot of options.

a sounservo is actully a servo?
United Kingdom
#38  
If set up correctly you can use the sound servo control to turn a digital port on and off, this can then directly drive an LED or be used in conjunction with a TIP switching circuit to drive many LEDs
#39  
Sound servo is software feature in ARC... it's not an actual servo possessing physical sound qualities...

wow thats great ,i dont have to solder anything then.
sofar i have 3 leds i wanne use.
one red for the mouth.
and two pink.


i like the look off the leds and you dont see them


i found these resistors.

resistor 330 1/4 watt
