Arduino and servo motor

Hey;

I have this code to active servo motor, I want regulate the of the motor with binary values between 0-255. someone can help me please?

clear a;clear s; 
a = arduino('COM10', 'Mega2560', 'Libraries', 'Servo');
s = servo(a, 'D4', 'MinPulseDuration', 700*10^-6, 'MaxPulseDuration', 2300*10^-6)
while(1)
    writePosition(s);
    current_pos = readPosition(s);
    current_pos = current_pos*180;
    fprintf('Current motor position is %d degrees\n', current_pos);
    %     pause(2);
end

Hi Dekel,

From what I understand you are trying to adjust the position of the servo with input ranging from 0 to 255.

angle = 50 %You can take any value from 0-255

angle = angle/255 %This changes the value to the range of 0-1

writePostition(s,angle);

Now if you want to read the value in range of 0-255 just multiply 255 to current_pos instead of 180

current_pos = readPosition(s);

current_pos = current_pos*255;
