Hello, sometimes you cant see the forest for the trees.
Working on a 1/350 scale model of the Enterprise with a friend. He wants lights and sound effects. Everything will be lit with 5v LEDs, and using a Music Maker Shield to play MP3's. Here's the sequence:
On power up, play a startup noise ONE TIME (track001, works good)
Rocker switch, two positions, starts in the OFF position.
When you close the rocker, it plays a startup sequence and audio track002 (handleSwitchCruise), and lights up the LEDs in sequence with a few second delays in between them. (should be the IF portion of handleSwitchCruise). After that, it should continiusly play a bridge sound effect as a loop (which it does).
When you open the rocker, it should play track022, and then after a second or two, shut off all the LEDs (the ELSE portion of handleSwitchCruise). The background bridge noise should NOT play here (which it does).
Funny, everything works - but my IF and ELSEs are backwards. It does the ELSE section when you close the rocker, and then the IF portion when you open it again. Im sure its something stupid and minor, I just cant see it.
