Dual indicator leds

[Kipper4]

Guys help an old man out.
When the boxes arrive I want to box up my drive.
I want to use dual indicator leds for bypass/on.
3mm reds.
How do I wire them?
Series. Parallel ? And what about clrs.
They're hopefully going to be fitted to the box though a tight fit hole then the tops sanded off flat so they shine through the vinyl label.
Thanks
Rich

Sounds like you're planning some glowing red "eyes", am I right?
I did something similar, but not with a vinyl label:

Anyway, you can do either series or parallel.  With parallel, you should give each LED its own CLR (any slight difference in Vf will show otherwise).  I'm series, you can add your voltage drops, subtract that from your supply voltage, and divide by the current you want.  You may want to test brightness through your label to decide on your current.

"Sounds like....."
Busted.

How did you wire the ones on the Trump pedal.
That was you wasn't it?

Thanks for the help. Getting the brightness right I'm sure will be a struggle. I do have a gash enclosure I could experiment on though.

Trump pedal is not mine (I hope it was an Uglyface circuit). 
I'd say save a penny and wire them in series.

Hey Rich!

In series you would have double the voltage drop, so 3.4 form 9 which will be 5.6 / 5mA (lets say) = ~1k1 (just use a 1k, close enough).

I originally thought you were asking for one to be on when bypassed and the other to be on when active and had a different circuit in mind, but it appears you would like the both on or off.

Cheers!

Yikes only 5v6 left to run the circuit right.
I'll tell you what though Lawrence I wouldn't mind seeing the on/bypass led each, circuit idea.
I might just change my mind and go with different colour leds for each eye.
Thanks mate
Rich

No....  5.6v across the CLR.  Your circuit will be separately across the whole 9V. 

[EBK]

Here's a little hint for two alternating colors, which demonstrates why to use separate CLRs normally for parallel LEDs.  If you use a single CLR and connect that to a parallel combination of a red LED and a green LED, only the red one will light.  Disconnect the red one (with, say, a SPST switch) and the green one will light.

Yer of course. My bad.
I feel really dumb even asking this beginner question. I do have google but I know you guys will second guess me. Provide opinions and methods I can't even get my head around this evening.
So thanks guys again sorry I can't think straight.

[EBK]

No judgments here.  Ask all the questions you want.  We'll keep you thinking straight enough.

[Groovenut]

Here's one way to do it


Or this if you want to save a part

Or this to save another part and have control over individual led current.

Or if you want to skip the transistors, this works too

[Kipper4]

Thanks guys I'm gonna bread board some stuff before I box it.
My heads a bit clearer today.

[EBK]

Great.  I'd suggest starting with Lawrence's first version: 1k resistor and 2 LEDs, all in series.

That's the arrangement I was mentioning yesterday.  It will only work if LED1 has a lower Vf than LED2, of course.  For example, LED1 = red and LED2 = green.

Thanks for mentioning that Eric. I should have stated that LED1 = red and LED2 = green. If you use two of the same LEDs you can insert a diode (1N4148) in series with the LED that is // to the switch.

I might just change my mind and go with different colour leds for each eye.

You could also consider using bi-color LEDs and switch both eyes from, say, red to green.  I'm actually using RGB LEDs for my Clippy pedal to show different modes with different colors.  Tons of possibilities.

[Kipper4]

I'm going with 2x red 3mm series with a 1k CLR
cheers guys

I'd triple guess that Rich would want envelope control of the colours.

...mood detection is it?

Trump pedal is not mine (I hope it was an Uglyface circuit). 

That should be a signature line. Or in the joke thread, at the very least. Made my "smile of the day" moment.

Thats not a bad idea to add an envelope detector and light up the leds on playing.
Only trouble is it wont tell the player if its on or not until its too late and your solo sounds lames and you die of shame.

I goddam wish I had a pedal that could read my mood and adjust the settings accordingly.
Thanks to Eric, law, and everyone for the boost and thinking for me.
