Stopping a servo while loop with
Question
I am building a project that involves a servo and an adifruit circuit playground express. My goal is to have the board go through a light sequence, have the servo turn 15 degrees, turn back 15 degrees and then repeat after a 10 second delay while being initiated by the A button. This will go until the B button is pressed essentially breaking the while loop that was entered with the press of the A button. I've thought of having the while loop check for if a value is still considered 'true' each time it loops which led me to believe I should try a 'switch-case' idea but I was not sure what to put in the switch(). Here is some of what I have. It's only 2 IF statements but the 'buttonPressedA' if statement runs infinitely without the possibility of breaking out of it. Help with this would be really appreciated.
// and here, we, go. (just like the joker says it)
#include <Adafruit_CircuitPlayground.h>
#include <Servo.h> // servo library
#define NEOPIX_PIN A2

Servo nohands; // creating an object so reference the servo library, no hands. get it. cuz you're not using hands... alright that's it.
int pos = 15; // varible to store the servo position. ALSO HAS THE START POSITION FOR THE SERVO
bool leftButtonPressedA;
bool rightButtonPressedB;
uint8_t pixeln = 0;
Adafruit_CPlay_NeoPixel strip = Adafruit_CPlay_NeoPixel(NUM_PIXELS, NEOPIX_PIN, NEO_GRB + NEO_KHZ800);

attention to the fact that when you press B the microcontroller is executing one of the delay lines, therefore doesn't check the if(rightButtonPressedB) condition nor B button state.
Try this function instead of delay(x):
void my_delay(int x):{
int i=0;
while(!rightButtonPressedB and i<x){
rightButtonPressedB = CircuitPlayground.rightButton();
delay(1);
i++;
}
}
