Predator cannon

I have been trying to get it to work with the original write up here:
www.instructables.com/id/Arduino-animatronics-make-your-awesome-costumes-m/

No success so I have ordered the exact parts in the walk through. If no success there then the updated codebase the arduino uses is incompatible with the older code.

I have had some success with this code:
blog.underc0de.org/arduino-wii-nunchuck-servo-motores/
(y axis works on both, but not x on one and y on the other.)
I think some noise from the servos has something to do with it even though they run on a separate power supply.
My spanish is not as good as I would like it but I think I got the gist of what he was saying in the code comments. Learn one romance language and you can puzzle most of the rest out.

The adafruit servo shield demo library codes the run loop like this:
void loop() {
// Drive each PWM in a 'wave'
for (uint16_t i=0; i<4096; i += 8) {
#ifdef ESP8266
yield();
#endif
for (uint8_t pwmnum=0; pwmnum < 16; pwmnum++) {
pwm.setPWM(pwmnum, 0, (i + (4096/16)*pwmnum) % 4096 );
}
}

I am having to chew on things slowly as I get my head wrapped around things. The above code snippet drives all 16 motors but something is not right. Also bear in mind this is my very first trip into dealing with servos.

I got a working motion tracker.

I got a working smart gun electronics set

I got a working streaming web camera that I intend to build into a streaming helmet camera.

I just need time, but the research and ways to do it are so varied that, learning from scratch can be very difficult.

OK here are the code pieces I am working with:
