actually i want to move my robotic arm on different axis and for that i tried to build a class and write that code 

//Like for alphabet writing A

port.interop(address,1);    //to move up    

timer1.enabled=true;        // for delay
 
port.interop(address,2);  //to move horizontal

timer1.enabled=true;        // for delay

port.interop(address,5);     //to move down

timer1.enabled=true;        // for delay



now i dont know how to move my robotic arm on the half of up(vertical axis) and then draw horizontal line for A???
