Hi, I'm student we have a school project and I wanted to do RGB globe I did a lot of searches and I find a PCB with some complacency and I didn't know one of them I have circulated in red

OK

none of the pic's are clear or close up enough to tell what those 2 components are for sure.
most likely they are capacitors, but impossible to confirm :(

i need just the yellow thing the silver one is
Quartz 16MHz i can tell from the arduino

How can you make this project without a schematic, parts list, pcb design and parts layout diagram??

as I have said .... we have no exact idea since you cannot supply better pic or information
the yellow things look like capacitors but what their values are who knows ????

Sires . . . . . . . .

Applying a little NASA enhancement procedural, using spot averaged digital enriching and a bit of pixel dithering and just before pixelation . . . which has been offset with blending . . . . we can then come up with:

View attachment 32757


The naked picture looked like 4 yellow LEDS, closer in, it then started looking like them being fused together as being dual sets.
AND THEN . . .it finally looked like two El Menco / Sprague epoxy dipped silver mica capacitors. BUT just being void of their typical reddish brown coloring.

They are located right up against the crystal and they are usually in the popular 32 pf on down to 18 or 22 range that I typically have seen.
This must have purposely been some large scale / size component usage, as now a days it would ALL be micro sized surface mounts.
Here is some old breadboarding, and you can see their utilization of a 22 pf disc ceramic pair with their 16 megglinghurtz xtal.

What say ye. . . .?

Alsohowsomever . . . . doesn't it look as if one of those blokes is so polluted out of his mind, that he is trying to use a 5/8---3/4 in wrench on a LED . . .vice the side gimbal assembly.

The funniest little capacitors I have ever seen. Twins?? I am a twin and I don't look like that.

the yellow thing on this pic is totally different to the two yellow things you circled on the first image you posted

this round yellow thing is a trimmer capacitor ...
yellow is likely to be a 6.8p to 45p trimmer
