Using spst momentary NO switches for a game controller mod. Switches will trigger a keyboard keypress. Toggle off to on, on to off.
Is it possible.... easily... to have the NO switch complete the keyboard circuit AND toggle a relay to drive an Led to show the on/off state that pressing the spst switch controls?
Trying to have a visual representation (led) of the "on" state as set by the first keypress. And have the 2nd spst press cancel the led indicator.
Would need a dozen of these circuits so simplicity and low part count is important.
I know I can buy a ready made usb interface which will support rotary encoders (a 2nd project ), but can I accomplish my original idea with a small number of components?
Thanks
