I'm making a speaking skull. Found lot's of info, and finally I've got it to work.
I am using an arduino mega with a adafruit MP3 shield VS1053 on top of it.
It works fine, but to (re-)start it you have to press the reset button. I want the arduino on, and as soon as a button is pressed it start to play the words.
I did found an answere on Reddit: https://www.reddit.com/r/arduino/comments/2bdurt/starting_the_loop_with_the_press_of_a_button/
They proposed :
void loop() { while (digitalread(pin) == LOW) {};
while (1) { // do stuff here, the loop will always repeat } }
or even better at the bottom of the setup()
while (digitalread(pin) == LOW) {}
Then you don't need "while (1) {...}". This is in the code
I tried to put the "{" and "}" almost every where, but I don't get it to work.
BTW: the button has 5 v incomming from the mega, outgoing 10K to gnd and a connection to pin 2.
What do I wrong?

Scope is: when skeleton is outside the coffin, the jaw moves with the spoken words.
This will be activated when the end switch is made. (Have to implement this switch).
jawservo works and eyeleds are working.
