WEEK 5 FYP 2

Title of activity:

Proposing the circuit for etching in PCB board. 

OBJECTIVES:

Showing the circuit for etching purpose.

CONTENT/PROCEDURE:

Here, I would like to present the circuit drawn after the schematic circuit. This is where I should print on the PCB board.

ANALYSIS:

this layout for ecthing is the motor driver Circuit.

below is the pcb layout for PIC circuit for this project.

CONCLUSION:

by using this etching for PCB it is more easy to design the circuit and to solder the circuit. it ease our problem and more easy.

WEEK 4 FYP 2

TITLE OF ACTIVITY:

Do the hardware of this prototype.

OBJECTIVES:

To make the hardware for prototype so its can see the mechanical part of this project.

CONTENT/PROCEDURE:

1. Try to make the hardware like this picture.

2. Make the prototype by using aluminium.

3.  make the base by using of the plastic.

4. use screw to make it complete.

5. put a dc motor to make it function.

ANALYSIS:

 do you think what it will be? can you imagine my prototype?

this is my prototype after i redo many time due to mechanical problem.

CONCLUSION:

from doing this mechanical part, the design is the important thing in this part. make sure all the material, size, design is suitable and fix with objective in this project.

WEEK 3 FYP 2

Title of activity:

Block diagram and flow chart

Objectives:

To explain clearly about process of this project

Content/Procedure: 

1. list all the input and output.
2. State the process of the project.

ANALYSIS

 The switch is the input of this project. The users give instruction by using this switch. Then the input from the switch is fed to PIC micro controller. The pic microcontroller will control the program and give instruction to the DC motor control which is the H bridge circuit. This make the dc motor get instruction and perform the results in wheelchair which we can see the results in mechanical performance. PIC that will use in this project is PIC 16F877A that working like a brain to receive the input from the switch and give instruction to motor to operate. It also produces output to the blinking of Led and LCD’s display.

The flowchart is discussed about the whole of process of project. This project will program that this prototype will operate when get command from the user by switch. Then the command from the user is the input for pic program and will produce output which is LCD display, red and green led that act as indicator, the movement of wheel and reclining’s part.

 CONCLUSION

The blcok diagram and flow chart must correct so the flow or process this project can be smooth. InsyaAllah.

WEEK 2 FYP 2

Title of activity:

Explaining the equipment/ material that will used in this project

Objectives:

To make a clearer vision on what equipment that i will be use.

Content/Procedure: 

1. Do research before select the equipment.

2. List down the equipment that i will used.

3. Go to Jalan Pasar and other store to get and buy my things.

Beside that this is the component that i need in my motor driver circuit.

this component, equipment is buy to fit the specification that i need for my project. 

Conclusion

nothing is easy. the actually many time i rebuy because component damage when testing. its all because try and error until success ;)

WEEK 1 FYP 2

Title of activity:

Research on the circuit

Objectives:

To make a clearer vision on what circuit that i will be use.

Content/Procedure: 

1. Since this week is the first week of new semester, I got a lot of issue with my time table. Hence, I don't have too much time to meet my advisor. 

2. But, although I got a lot of things to be done by week 1, I still make a research on schematic circuit through the internet, reference book at library and also asking to my friends. 

3. Based on my research i need to find the PIC 16F877A circuit which is can control my project and motor driver circuit to control direction of motor. Circuit of PIC i use the common circuit but i add on some switch and lcd panel in the circuit as input and output for this project.

4. Then i find H-bridge circuit that use L298  as my ic motor driver and i need to construct the circuit based on data sheet that i got from the internet at website solarbotic.

ANALYSIS:

This circuit of motor driver L298 is important to control the direction of motor for movement of wheel and the movement of reclining part.  I choose, the stage of motor operated can see by the blinking LED as an indicator in this project. I try stimulate in multism and look the output before use in my project. after that i know this circuit is suitable with my project.

All the program will be setting in Proteus by using this schematic that contain PIC circuit to run the program.  From the beginning there have mention about the wheelchair need the instruction from the user to operate the wheelchair. Therefore the programming is needed in this project. The microcontroller is using to program the project by using assembly language. The project is start when the user gives their instruction using switch whether to move the wheelchair or to recline the wheelchair. Then the programming is needed to run the dc motor. The dc motor is controlled by using H bridge circuit like i said before.

Conclusion:

The simulation of this circuit is going well, Alhamdulillah so i will use this circuit in my project.
