LED Amp Status from momentary switch help

[Steelroller45236]

Hi All,

I've given up on trying to get the tap tempo LED project to work....it involves a microcontroller....too much for just conveinence....

So now I'm trying to at least resolve this problem. I want LED status on my floorboard to show channel status of the amp. However, the switch to make the amp change channels is a momentary NOT a push on/push off....

Ok, It is basically a momentary switch that triggers channel switching on a guitar amp. I have a 9v supply at my pedalboard for powering effects processors.

So, we have a momentary contact switch that needs to light (and keep on or off depending on status....I would like to use a dual color LED (green/red) to show channel status. A push on/push off will not work because you have to hit it twice to toogle the amp then.

I would imagine it to be some type of latching IC ... is that correct?

But again, I am VERY newbie.... so handholding or oversimplification is a good thing in my case... I can follow a schematic fairly well though... unless it becomes super difficult...

Is this enough info to go on??? Thanks

Got you covered.

Check out the "Wicked Switch" project on our moderator the tone god's web site.  There's an option to use a momentary switch.

You can use this great little 4049 ckt by R.G.

As the schematic shows, place one LED before and one LED after the last inverter.  This will give you an alternating LED.



This has become my favorite ckt to use with tactile switches to control relays.

Hope this helps!
