WEEK 7

Title : Components and parts of project

Introduction 

Each project to be developed has a distinctive design. This is because of the design phase of the project is one that should be in developing the project. The purpose of the design phase of the project is to achieve the specific goals, specific tasks, and certain results, so it does not run away with the project objectives. In all the tasks for this week, it also includes a few inquiries for parts / components that will be used in the project.

Objective

1. To design the project coincides with the main objectives of the project.
2. To investigate the material / component / equipment that will be used throughout the project.
3. To combine all the materials obtained according to the designed project.

Problem Encountered


Designing efficient project requires experience in certain fields and basic knowledge of other matters related to the design is required. Without these criteria, it will be quite difficult to design the project. However, with reference to the some websites it can also give you some ideas that are very helpful for designing the project according to the required design. This is because, if the design is not perfect incubator based characteristics are required will cause damage to the eggs during the hatching eggs. Design an incubator influencing the temperature and humidity in the incubator, if not taken care, it will damage the embryo in the eggs before they hatch.In the find for materials that will be used, the type of material and product specifications required in this project should be identified to prevent material from getting damaged during testing and building / fixing / circuits. However, this problem can be solved by doing a study / research is needed and record important data for used in the future.

Project Description

In designing the project some important elements should be taken. Following a few questions that should be taken into consideration in designing the project. Among them are : -

1. What is the concept/theme of the project that want to designed?
2. What is the type of material that suitable to used? (i.e plastic, wood, steel and etc).
3. Project size - how large project size that needed accordance with the project criteria.
4. What is the type of controller that want to used? (i.e u-controller - PIC16F877A,  and etc).
5. What is the materials that needed for I/O?
6. How much the amount of voltage/current needed for each electrical/electronics materials?

Based on the list of questions above, the concept is simple to use and compact.Type of material that will be used for the design of incubators and protect the circuit is from plastic materials. The size of the design project is small eggs incubator for easy to control the temperature inside the incubator and simple to change places.In term of their controller, PIC 16F877A - Main Board will be used as circuit controller.Why PIC16F788A to make it the first choice as a controller circuit in the project? It is because cheaper and one a simple way to control circuit includes a code of their programs. Moreover, to practice what has been learned in the introduction of micro controller subject to the project.

Below is the materials that will be used for I/O and the additional materials including with the specifications for each materials will be listed such below:-
