WEEK 14 - Thursday

ANALYSIS AND DISCUSSION

            Based on the mini project development it can be analysed the problem that occurs during the project progress. The main problem on this project is the hardware doesn’t working and fuction as well as in simulation. During the hardware development, the microcontroller seems not operating and the LCD light on but only display the blank screen with no word on the screen. So, to prevent this problem occur again in the future the troubleshooting based on the coding is checked. There is no error was found. The circuit is constructed with very basic component to make sure all components are test and worked. The circuit is including four push button as input, IC8051 with basic component, and LCD which based in proteus simulation. So the connection on the hardware is checked to make sure the circuit is connected. The result of the trouble shooting is there is no problem on the connection circuit. Then LCD is checked because of the sensitivity of it. However the LCD only light on with no word on it again. So to short the time taken on the circuit, the IC 8951 is change to silicon lab toolstick850 in the hope the changing of the microcontroller can function the circuit. As for the silicon lab toolstick850 the other problem occur is adjustment of port used due to the port for IC 8051 in proteus is not the same with silicon lab toolstick850. The same problem occur again when silicon lab toolstick850 is connect to the circuit, the LCD didn’t display well. All the project progress, video, picture and final result was publish on our blog addressed at, http://digitalspeedometer.blogspot.com.

CONCLUSION

To be conclude, the objective of the mini project has not been achieved with the failure on the hardware development. However, this project provide a meaning lesson and experience on the programming project. This mini project encouraged students to do a lot of research about the C language on how to program a simple project. Moreover, student also can developed the skill to make hardware as an application of microcontroller system. So, students must be well prepared in terms of programming knowledge and hands on for the hardware. The project must be simulated first before hardware is work on. This is important because to troubleshoot in simulation is quite easy as being compared with trouble shooting on the hardware. Only when the simulation is completed and done, then the hardware can be continued progress to develop. This project give students lot of knowledge not just on how to coding a program but are also exposed with the electronics devices and components such as LCD, resistors, capacitors, microcontroller and etc. As the microcontroller silicon lab toolstick850 is quite more challenging than IC 8951. Lastly, this project really helpful for the students and can be applied for the future career.
