arduino for proteus

                                               arduino for proteus 

first of all you must download the arduino proteus library from

http://j.gs/756O

then you open the library file and then copy it and past in on

C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\LIBRARY


after you can use it .

                 if you use the ultrasonic sensor you must upload the 
this hex file to ultrasonic in the proteus . the hex cord in hear
