I have to wire two leds that indicate On/Off status for a stompswitch.
Do you think this one below is ok? (excuse me for the bad picture :icon_mrgreen:)

May I do it in a different way? Is it possible to add two leds in Darron's layout? (http://www.diystompboxes.com/smfforum/index.php?topic=56137.msg433559#msg433559)
Thanks in advance

No, it should be like this:

Eliminate the trace with the red "X" and replace it with the trace in blue.

I don't think so. You'll have to rearrange it.

You can use the one posted by Skreddy, but modified like this:

Eliminate the traces marked with the red "X" and add the trace in white and the second LED with the trace in purple.


Good luck,

CG ;D

many thanks for your replies, I'll try something you have suggested!  ;)
Just a question: the scheme I posted is wrong because it may cause popping during switching?

Hi! Here's the final draw. It's the wiring of the whole project.
The first board is a generic effect. The status indicator is made with a single led. The layout of this part is the one suggested by Darron  ;). The out of this effect is driven to the send/return loop of other effects. The effects chain is preceded by a preamp. There are two leds: the first one indicates lights up if the signal passes through the effects loop, the other one, turns on when the signal goes directly to the output. This second section has been designed thanks to CG advices.  :)
Do you think are there any mistakes in the schematic? Thanks again!
