That was exactly what i was looking for Hans Milton i tried things like

out=Animate[Sin[x],{x,0,2 Pi}]

but it didn't seem to work , now i have all the control that i want over my Arduino

is there any other functions like animate but give pure integer output?

I do not understand what you mean by giving pure integer output. If you want the x,y data, then the command to use is Table

data = Table[{x, Sin[x]}, {x, 0, 2 Pi, .1}];
ListPlot[data]

If you meant something else, may be you can clarify or give example of what you are looking for.
