Problem statement of the project~~

Problem statement :
The purpose of this circuit is we need to use application of the light sensor and the timer component to switch to another load in the faster speed. The light sensor circuit that can act as the switch for the circuit and also for the load, it can switch the circuit and the load on and off in a faster speed. This circuit most probably is designed for the security system and the trigger camera. This is because the circuit can detect the change of the light by using the sensor in order to give the instruction for the load and let the load to operate it function.

*We should really appreciate this application since this application bring lots of advantages to us in making our lives easier~ Thanks for the inventor!!!

Main + sub-objectives of the project~

Main objective :
To learn and apply the function of 555 timer IC in the real world application

Sub-objectives:
a)To learn the function and the operation of the 555 timer IC.
b)To investigate the flow and the functionality of the circuit.
c)To learn simulating the circuit by using the software.
d)To work the project in a team and finish it systematically.
e)To learn to work out the project in the lab by using the component according to the given circuit diagram

Daily report (30/9/2009)

Activities:
-Discuss about the main,sub-objective,and problem statement of the mini project.
-To find the solution for the main, sub-objective and problem statement.
-To find the additional source and information about the project.
-Take the components and measure the true value of the resistance and capacitance.
-Update the blog.

Place:
Faculty Engineering and Environment Building

Date:
30 September 2009

Time:
11.00am-12.30pm

Task leader:
Yii Wen Wen

Assistant:
Chong Kim Soon

Working flow process:
First, we start to discuss about the main and sub-objective of the mini project. We refer to the information we found from the internet and textbook to understand the flow of the circuit and the application of the circuit.

After that, we take our components from the laboratory. Then, we measure the true value of the resistance and the capacitance. Besides, we take some photo for the components and some photo when we measure the resistance and capacitance.

Finally, we update our blog by uploading the pictures and the main, sub-objectives and the problem statement of our mini projects.

Tomorrow we will try to stimulate the circuit in the circuitmaker and trying the functionality of the circuit in the lab.

Wish the process of the our project can be moving on very well~~

Daily report (29/9/2009)

Activities:
-Discuss with each other to create a blog.
-To add the information into the blog and email it to the demonstrator.
-To find the source and information for the project.
-To find the solution for the main, sub-objective and problem statement.

Place:
Perpustakaan Tun Seri Lanamg (PTSL)

Date:
29 September 2009

Time:
8.00pm-9.30pm

Task leader:
Yii Wen Wen

Assistant:
Chong Kim Soon

Working flow process:
First, we starting to discuss the way to create the blog and the name for the blog URL. After that we start the do the theme and the basic information of our blog. The blog URL’s name and the theme was settle while the information of the project was upload by Chong Kim Soon.

After that, we try to find the information about the project from the internet and we also find some reference from the book in the PTSL. We are trying to understand the working process of the circuit.

For the main, sub-objective and the problem statement, we both agree to
complete it by tomorrow, because we both are not familiar with some part
of the component inside the circuit diagram.

*First day of starting to do the mini project, quite exciting and worrying about the processing of the project, but we will sure put all our effort in this project in order to make it sucessfully~~

YEAH, let start the LIGHT SENSITIVE TRIGGER project!!
