Thank you

What part do you need help with? If you want someone to just do it for you then you can ask on the Gigs section and offer to pay someone. But if you want help them that implies that you are going to do at least some part of it. In that case you need to be a little more specific about what part is confusing you.

This code is making a mistake. It only rotates 5 degrees very slow::

pins={'D8', 'D9', 'D10', 'D11'};
steps={'1100', '0110', '0011','1001'};

steps_size=size(steps,2); %steps = 4

for i = 1:50

step = steps{mod(i,steps_size)+1}; % step=1,2,3,4

for j=1:4
writeDigitalPin(a, pins{j}, str2double(step(j)));
end

pause(0.01);

end
