OK, I added some more logic. I added a kill sequence after launching any sequence over a 20 second span. And I added a volume control routine. I also cleaned up the led and laser logic and separated out the sounds.
I did discover that mplayer has a 1-2 second delay on processing any given sound file. aplay seems to be quicker but you have to have PCM or float encoded wav files to use with it.
to invoke the killing of a playing song I used this line in the script:
os.system("pkill mpg123")
to invoke volume changes I used this line in the script:
os.system("amixer set HDMI -- -2000)
the number is basically figure representing the db level, -2000 is minus 20 db.
It was a fair bit of trial and error but those helped a lot in case I had to stop a file from playing in case it either, triggered someone, was inappropriate for a given situation, or silence was needed/required.
The LED's are going to be activated with elechawk rc switches. They seem to be the most simple hardware solution to provide power and light amperage needs for super bright led arrays. THey are not made state side that I can determine and have submitted a product suggestion to adafruit as I will lay odds they could sell one for 5 dollars and outdo everyone on the market period.
leds are as follows currently:
6 is the trilaser
15 is left cannon firelight array
4 is left cannon trilaser led light array
10 is right cannon light
11 is right cannon laser led.
btn a activates light sequences on left cannon. btn b activates light sequences on right cannon. btn Z activates lights on both cannons. btn c activates the tri laser array.
0 is left travel servo
1 is left tilt main servo
2 is left x tilt servo
3 is left y tilt servo
13 is right main tilt servo
14 is right x gyro servo
7 is right z gyro servo
I cleaned up unused servo numbers causing erratic performance with led and servos.
Servos and lights are all deactivated and placed to neutral start positions at script beginning.
it then asks to activate the wiimote.
status updates are then displayed to screen
hitting home button moves armatures to active postion and enables movement for x/y/z axis control units
hitting home again moves servos to start positions.
hitting plus and minus together exits script afte rmoving servos to start positions.
if battery is belowy 79 reading servos moved to start positions and wiimote vibrates. Any lower battery value causes responsiveness issues and quirky behavior I have observed if unit approaches a value of 70 out of a max sub 200 value.
Buttons A, B, C, Z control lights
joystick on nunchuck controls left armature
gyrosocope on 9dof board controls right armature.
all other buttons used to play sound effects.
