In the code, configure Z_Pin to pull-up input mode. In while cycle of main function, use analogRead () to
read the value of axis X and Y and use digitalRead () to read the value of axis Z, then print them out.
while(1){
val_Z = digitalRead(Z_Pin); //read digital quality of axis Z
val_Y = analogRead(A0); //read analog quality of axis X and Y
val_X = analogRead(A1);
printf("val_X: %d ,\tval_Y: %d ,\tval_Z: %d \n",val_X,val_Y,val_Z);
delay(100);
}
