Need help with LED selection

Parts Questions

I’m just getting started playing with electricity so I’m unsure which LEDs to get for my SEQ…

I got SmashTV’s DOUT kit (btw, very promptly and neatly shrink wrapped too!) and it came with 220-ohm resistors.

If I picked up some 2.1V min, 3.0V max (@ IF of 10mA) LEDs, am I right in thinking that this will be OK with the R220’s?

I should be getting around 2.8V/10mA to each LED. Is that suitable or too close to 3.0V for the R’s tolerance (5%)?

Anyone have a favorite diffused LED to use in these projects?

The LEDs dont mind if you push them with 5 Volt or more. The 3 Volt max you stated is just the maximum brightness voltage, I think.

So, for ~ 10 mA (min) 220 Rs are OK cause they will give you about 25 mA (5Volt/220)

Greetz!
