i hv made a robotic arm drawing ,with 3 servos and i want to communicate with servos serial and send specidic angles.
my code is
function [] = ServoAngle(Theta1,Theta2)
L1=0.065;%m
L2=0.125;%m
a=arduino('COM3');
a.servoAttach(9);
a.servoAttach(10);
px=L2*cos(Theta1+Theta2) + L1*cos(Theta1)
py=L2*sin(Theta1+Theta2) + L1*sin(Theta1)
a.servoWrite(9,Theta1);
a.servoWrite(10,Theta2);
plot(px,py,'r.');
xlabel('Px','fontsize',10);
ylabel('Py','fontsize',10);
pause(1);
end
without matlab only with the arduino i could send the microseconds (with writemicroseconds command) that i want, and servos does exactly the degrees that i want. but my project desires to use matlab and arduino to make the robotic arm ,so i want to communicate serial with arduino but i dont know how ?? i want to tell me the procedure to do this and some code... im interested to understand matlab-arduino serial communication and start change my code
thanks!!

The code you show looks plausible for the old arduino support package from the File Exchange. For the current arduino package, you should create two servo objects and readPosition() or writePosition() to the objects.

The support package for R2014b onward needs to be installed; see http://www.mathworks.com/help/supportpkg/arduinoio/setup-and-configuration.html
