Week 12: Troubleshoot Project

Week No: 12
Date: 13/4/2012


Title of Activity: Troubleshoot project


Objective:


1) To find out what make the project did not function like we intend it to be.
2) To repair the error that occur so our project can run smoothly.


Content / Procedure:


1) Check all the connection between the circuit
2) Check all the IC used in the circuit
3) Check power supply for main circuit and GSM modem
4) Check the load / motor
5) Check the program that we have write




Result and analysis:


1) Connection between all the circuit and between GSM modem are in good condition, there is no loose cable.


2) All the IC used in the circuit like MAX 232, ULN 2003 and PIC18F452 are in good condition, no broken pin and did not burn.


3) Power supply for the main circuit and GSM modem is also functioning because when we check the input voltage at the main circuit and the GSM modem with multimeter it shows reading.


4) When we test the motor with direct supply, it run as usual and this means it's in good condition.


5) Lastly we have to check the program that we write, because of everything in the project works properly that's mean the only thing that cause the malfunction in our project most likely because of the program. 


Conclusion:


1) It is certain that the error in the project is because of the program that we write.


2) We have to check back the program that we do, because there could be some mistake at the AT command and the protocol that we used in the program.


3) It likely for us to make a mistake while writing this program because it is the first time using the AT command and the telecommunication protocol.


4) Due to lack of time, we could not found the error in the program, thus the project cannot functioning according to our plan.
