Still Troubleshooting circuit.(WEEK 12)

In this week,we rushed back to level 4 to meet the technician to reprogram our PIC.Luckily,it was successful.Now we can try to troubleshoot the circuit again with the PIC functioning.The program that we use is from the EPE magazine.However,after putting the programmed PIC into the circuit,only the PIEZO SIREN and HOLD LED was working accordingly.We still did not know what is the problem that cause our circuit not completely functioning.

After a few advise from our friend and lecturer,we go meet the technician that program our PIC.And then she tell us that the program need to be compatible with the circuit which is the component that we used must be exactly the same with the component in the magazine.

As a conclusion,we can say that our circuit was partially function.Only PIEZO SIREN and HOLD LED was working correctly.When try to troubleshoot the circuit,we found no problem about the connection or about the soldering part.The current flowing in the circuit also correct.But the programmed PIC was incompatible with this circuit so its not fully working correctly.

Troubleshoot(WEEK 11)

After finishing constructing and soldering the circuit,we troubleshoot it to detect any problems.At the beginning,from our point of view,the circuit are well constructed.A few part of the circuit are functioning.Still,we have a problem about the LEDs and PIEZO SIREN.Both of it doesnt give out any output.After a few correction were made,the LEDs and PIEZO SIREN are functioning.But,we still did not test the circuit to its main function.This is because we did not programmed the PIC yet.


In the same week,we go to level 4 and meet the technician and ask them to programmed our PIC.After that,we put it to the test.Firstly,the siren are working well,one LEDs are working and others are not.And then suddenly,all of that turn off.After a few inspection,we found that the PIC was burned.Without any other PIC for our backup,we rushed back to Jalan Pasar and buy a new PIC.

BUYING THE CASING FOR THE BOARD.(WEEK 10)

After finishing constructing and soldering the board,we need to find the case for the board.The casing is need to be weatherproof so it will keep the board nice and dry.The case for the swimming pool alarm are buy at Jalan Pasar.

This case is for the pressure sensor.This case is different compare to the one in the magazine because the case in the magazine are not sold in Malaysia.This case is alot more bigger in size but also weatherproof.The cost of this case is RM15.00.

This case is for the swimming pool alarm circuit.This case is available at Jalan Pasar.It is weatherproof,long-lasting and can withstand high temperature.The cost of this case is RM30.00.

Constructing Circuit and Soldering component.(WEEK 9)

This time,we start putting the component on the board one by one.But we having a problem when putting the IC socket on the board because the gap between IC's leg is quite small.Still,we manage to overcome the problem.

After finish putting all the component on the board,we then start soldering all the components.During solder,we had encountered some problem,which is when we try to solder some components's leg,its was accidentally connected with others component's leg.To overcome this problem,we use sucker.

Drilling the UV board.(week 8)

Borrowing the drill from our friend,we start drilling the board but the drill bit was blunt.So,we had to go buy  a new drill bit at hardware shop.After that,we continue drilling the board until all the hole that needs to be drill is finish.
