bolt would be best.

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?

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

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 found these resistors.

resistor 330 1/4 watt
