                Analysis:

                While doing this circuit, the most important thing that must be take note is the actual design of the component. If the design is too small, the component cannot be match with the circuit. From the picture above, we can see on the circuit a lot of jumper. It is because, the connection of the circuit while doing etching method is disconnected and to joint it back, we use jumper and testing again with multimeter.

                Conclusion:

                The circuit is show the interface between PIC circuits with output circuit. While the design, construct on PCB board, etching process and soldering all the components have done, the next process is to testing the circuit which is the circuit is function properly based on expected. So, this part has done and the objective is achieved.

                    Ø  The running program is same with others speed ( speed 2 till speed 5 ) of fan


                    Analysis:

                    In this part, before run the program in proteus and it is call as simulate. Writing language in MPlab must do first, when compile done and if have error it means the something wrong at the language but sometime the compile has success and when run in proteus, nothing display. Probably, the connection of input and output port PIC not related with language program, so checking and try again must repeated.

                    Conclusion:

                    For this project, the circuit is run full of expected and working properly. So, the next task will proceed and in this activity, the objective is achieved.
