I am hoping to set up an external warning led that functions as my stir+ does.
I have found a bi colored led that will light red when the leads are oriented one way and green when the polarity is reversed. I understand that the green led can be wired to the switch (pins 6 and 7) my trouble is with the alert led. I know I can use the mut wire as my alert ground but what about a positive lead for alert? Would the speaker + (pin 8) work?
I am not great with electronics but I would assume all positive leads would need diodes? Maybe all leads?
Are there any electronics gurus that can help me accomplish this project?
