Week 5

Title of the activity: Study programming of PIC 

Objective:

• To make the PIC operate
• To study about language program ( ASM language )

Content/Procedure:

• Study and define pin of PIC
• Study the ASM language
• Discuss with programmer

Pin i/o of PIC

Define port :

• Port A - sensor
• Port B - LCD display
• Port C / D – LED and connect to the output circuit

Program language:

                Assembly Language ( ASM )

Continue till end program……………………

Analysis:

Based on this part, before write the program also run of project, many factor must taken such as refer to block diagram, flow chart of this project and must define the input and output ( i/o ) port of PIC. So, for this project the port of PIC has defined. Port A for sensor, Port B for display, Port C and D for Led. Beside, for language to write this program, assembly language has selected.

Conclusion:

For this project, this is difficult part and must study hard because if write the wrong program or wrong command, the circuit not function properly. After study with programmer and do the research about the language, the objective has done.

Week 4

Title of the project:  Construct the circuit using electronic software

Objective: 

• To select the which one of the electronic software
• To construct the circuit of project

Content/Procedure:

• State the electronic software will use to design the circuit
• Design the circuit in the software

Proteus software

PIC circuit

Output circuit

Analysis:

For this part, much electronic software that use by engineering student for simulate their circuit such as Pspice, Multism, Proteus and etc. So, for this project, the proteus software has selected because in this project have a program and the proteus software has relevant compare with other electronic software. Beside, the main component that used is PIC, so it is already install in this software. Student should build all connection at the input and output pin at PIC. Circuit will design based on the block diagram refer step function. For the example at PIC 16F877A, it have Port A,B,C and D where each port have their own operation function. Student must define each port to make their operation based on the block diagram or planning.

Conclusion:

Using proteus software will help student understand to connect and design the circuit based on PIC performance.  In this work, connection between components is important to make circuit will operation smoothly when applying the program assembly language (ASM language). If the connection have a problem, this software will show where the connection wrong.

Week 3

Title of the activity:  Design structure circuit

Objective: 

• To know the design and construct of the circuit

Content/Procedure:

• Design the connection of the circuit
• Discuss with lecturer

PIC circuit

Output circuit

Analysis:

Before do the simulation on the electronic software, sketch the connection of the circuit on the paper must take first. The figure below show the design of PIC circuit and output circuit:

Conclusion:

Design the structure circuit is a main part before design the real circuit because to ensure the project work properly also know the direction of wiring between components and combination of both circuit. So, in this part, the objective is achieved.

Week 2

Title of the activity:  List of component

Objective:

• To know the main component that use in the circuit

Content/Procedure:

• Analyze the suitable component use in the circuit
• Find the component at the electronic and electrical shop 

Figure 1 : List components

Analysis:

After the research about the component has done, it is time to get the component at the electronic and electrical shop such as shop at Jalan Pasar. The table below show the list of component will use in this project.

Conclusion:

List of component it is important part for ensure the component will used is complete and no missing part also to avoid waste of money. So, in this part the objective is achieved.
