found the PROGRAM problem!  mea culpa.
i had a comma and space between pinMode and (yellowPin, HIGH)
these things are just a bit sensitive to syntax, eh?
(blush!, started working in computers in 1959 at philco)  smiley-red
thanks, all.

thanks, terry king.   good thought to try to use the local led.
will try it asap.

yes, the code works and is correct.
i'm new at this forum and not yet familiar with including the attachment.  i thiink  i know. now, looking at the bottom of the page.
i will recheck the code, it is from the suggested code in the adafruit project.  it also verifies and loads ok.
i'm on a different PC now.
more later, thanks, sam

leds with 100 ohm resistor, working with the 3-light project from adafruit,  the led on pin 10 works ok, full brilliance.
the leds on pins 8 and 9 half-light. i found no ac component on pin 10, but around a half-volt on 8 and 9 when "lit".
the program compiles and works ok except for the partial brilliance.
pin 10 is at 4.5+ vdc. at the arduino side of the resistor..(correct.)
pins 8 and 9 only go to 1.55 vdc at their resistors.
i swapped the pin numbers in the arduino to 6 and 7 and reloaded, same symptom.
and, of course, i swapped the led, to see that they are all ok on the pin 10 location.
i must be missing some setup on those pins, or what?
