PROBLEMS
- After week 7, some of problem has been detected. The major problem of the project is when the controller circuit is not working. After troubleshoot process has been made, the controller board still not working like simulation on Proteus software.
FINDINGS
- At the figure 5, shown that the new controller board has been used for this project. The controller board is buy from Astana Digital electronic shop. This controller board is working similar with the previous one.
RESULTS
- At the figure 1, the picture shown the process of the wiring on the cathode terminal. Heat shrink has been used to protect the wire from touching with the copper side.
- At the figure 2, the connector has been used to make an interface between LED PCB board and Controller circuit. All of the terminal need to be declare before the connection been made.
- At the figure 3, the simple programming as shown in the picture above is doing for make sure every layer of LED is running. Every port in the PIC 16f877a is row depend on the layer of LED.
- At the figure 4, after all of the process done, the result for 3D LED Cube is shown at the picture above. This project is running smoothly and more various feature will be seen on progress.

- To make a hole on PCB board.
- To etching a new PCB LED circuit.
RESULTS
- At the figure 1, after the hole at the PCB board had been made, the five layer of LED need to be plant on the sponge materials. At the right side of the picture, steel has been used to make the connection of the LED in series direction. The figure on the left side shown the 3D view and for the right side shown the upper layer of the cube.
- At the figure 2, cathode terminal need to be solder as a base of the cube. The picture shown the step to make it.
- At the figure 3, after all of the cathode terminal solder done, the cube of the LED will look as a picture above. The 3D view will be seen on the 45 degree angle.
- At the figure 4, the casing of the project will look as a picture above. The function of the casing is to make the LED look more brightness when turn on.

- To test the layer of LED with using simple programming.
- To construct a new PCB layout for LED board.
PROBLEMS
- After week 6, the several of problem has been recognize. The PCB LED Board need to be change because after the testing have been made, all of the LED is flash on simultaneously. It will be a problem when to make a text on the display LED.
FINDINGS
- The figure 5 shown the new PCB LED layout. It will shown that LED will turn on one by one and the questioning to make a text on the LED display is answered.
RESULTS
- At the figure 1, here is a sample of programming that will be used for testing every layer of each LED. By using C language MPLAB IDE, the simple program have been make.
- At the figure 2, by using breadboard, the connection of LED is show at the picture above. The jumper wire is refer to the ground (cathode) with series connection. At the upper side (anode), the jumper is used to make every LED blinking singly.
- At the figure 3, this controller has been used to transfer the programming to the PIC. The controller will be act as a interface between LED and PIC.
- At the figure 4, the picture is show the output result for the LED. At the left side, the output of LED show in parallel mode. Cathode terminal (ground) will act as a controller to make the LED blinking singly. For the picture at the right side, LED is connected series. It is happened because cathode terminal (ground) is in series mode (jumper wire).
- At the figure 5, the PCB LED layout need to construct again because a might of problem have been trace. The problem is, before this, anode terminal is declare as a controller. It will have a problem because on PIC 16F877A is only has 40 pins. Therefore, the new layout have been make to make cathode terminal as a controller for the LED.
PLAN FOR THE NEXT WEEK
- To etching a new PCB LED circuit.
- To make a hole on PCB board.

- To soldering entire of LED layer by layer.
- To show the step of soldering the LED.
RESULTS
- At the step 1, LED need to be bent as shown at the figure above. Anode terminal need to base by 90 degrees to the left along a line to parallel. For the cathode terminal, by using nose pliers make a 90 degrees downward bend.
- At the step 2, five LED need to place parallel as shown at the figure above. All cathode terminal need to be solder at the each of LED.
- At the step 3, after the process of soldering done. Multimeter will be use to check the connection all of the LED is good. Positive terminal need to put at the anode lead and negative terminal at the cathode lead as shown in the figure above. The picture beside that shown the LED's is in good condition looks like.
- At the step 4, the figure shown how the first layer of LED cube looks like. The process at the step 1 to 3 need to repeat until the five layer have been make. The picture beside that shown the five layer soldering has been done.
- At the step 5, testing and evaluate process has been show. By using multimeter and jumper wire, the testing process has been held row by row.

RESULTS
- At the step 1, glossy paper has been used for this PCB board etching circuit. Set iron at the maximum temperature and rub smoothly until all of the ink at the glossy paper stick at the PCB board. This process will take around 15-30 minutes.
- At the step 2, the glossy paper will look as a picture above, thats mean all of the ink is stick properly on the PCB board. After that, the PCB board need to put on the warm water around 5 minutes to make sure the PCB board more sticky.
- At the step 3, the etching process will be make by using ferric chloride chemical. This chemical need to mix up with a hot water and sieve around 30 minutes to make sure only the copper side are left.
- At the step 4, after the etching process done, the PCB board need to rinse by using water before the scrub process has been made. The PCB board will look as the picture above and multimeter has been used to check the continuity all of the copper to make sure all of the connection is in good condition. PCB marker will be used when the connection on the board is not connect properly.
