I want to declare 11 servo motors in my code. Is there a better way to do that than just declare everyone under each other. The reason is that i have a code that will set the rotation for one at a time. The best would be a list so i could iterate over which server i want to move.
Servo servo1;
Servo servo2;
Servo servo3;
Servo servo4;
Servo servo5;
Servo servo6;
//etc
void moveServo(int n,int deg){
servo[n].write(deg); //something like this
}
Consider using a specific processor / Arduino-board. In this thread there are references to using the Arduino 1280 board with the Arduino Servo Library to control up to 48 servos using a combination of hardware and software.
In C++ when you "instantiate" a class you are making good use of memory space as you do not really create duplicate code. All you create are copies of the variables necessary to support each instantiation. There should only be one copy of the code in memory. To iterate over each instantiation consider using a switch/case statement.
First: Your code would not work, since servo is not defined and thus not an array to iterate over. You would need to first define the array and then fill it with Servo elements.
Servo servo[11];
void setup(){
for(int i=0;i<11;i++){
servo[i] = new Servo();
}
}
The different Servo objects are created dynamically. In most cases it is bad to use dynamic allocation on a microcontroller with litte RAM, but it is ok, when you only use it once at the start.
