Side project.

Today I'm just working on the side that project which is science project. Here the pictures :

Quiet boring but interesting.

Thinking. Why it's burn.

I'm wondering why my transmitter burn. I have been thinking a few days but did not get the answer. I think it is not about the overload cause I just give 5V. My supervisor also ask me the same question, how much power that I apply then I said just 5V not more not less. Then why it happened?

The part that burn.

And, I still working on it.

Look simple but difficult.

Today, I try to test one of the sensor first, cause I need to know how it works. I try so hard but there's no output, means the output is always high. No changes with the output value.

The value didn't change.

Many times I tried but the result still the same. Then I make a solution, which is I need to study the characteristic of the sensor first. Because, the datasheet of the sensor is too simple. Here the datasheet : http://www.farnell.com/datasheets/9749.pdf

And yesterday I have construct the whole circuit. Here the picture :

First attempt.

Second attempt.

And my final conclusion for the construction is, I need to study on the sensor first. Because all the test that I have made didn't get the result that I need.

Almost done.

The sensor is almost done. I hope it will be finished by tomorrow. And tomorrow I will update the whole work that I have done today.

Airat2_Sensor

Today, I have a new task, which is I have to construct a new sensor circuit and the circuit is needed to connect to the sk40c board. Airat2 belongs to the (advance) micro mouse class of robots. These are designed as a research tool for artificial intelligence and use the "maze" as the robot's environment.
The maze is a standard size, set by the Institute of Electrical and Electronic Engineers (IEEE) and its construction and dimensions are laid down every precise set of rules.

Proteus.

Last Monday, I have learn Proteus. Before this I have learn this, and this is maybe just for my revision. I have known how to use it. We just had a few exercise and compile.

Quiz again.

Last Friday, I have done another quiz. The question is The Fibonacci numbers are members of an interesting sequence in which each number is equal to the sum of the previous two numbers. In the other words,
              F1 = Fi-1 + Fi-2
where Fi refers to the ith Fibonacci number. By definition, the first two Fibonacci numbers equal 1; i.e:
              F1 = F2 = 1.


Hence,
             F3 = F2 + F1 = 1 + 1 = 2
             F4 = F3 + F2 = 2 + 1 = 3
             F5 = F4 + F3 = 3 + 2 = 5
            and so on.
Write a program that will determine the first n Fibonacci numbers.
In this quiz, your tasks are:
1. to write the flowchart of the program in the next page.
2.to write, compile and debug your program to get required results.
   Example output screen:


Enter a positive number : 15
The Fibonacci numbers are : 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610
Press any key to continue

I have done it but I didn't get the exactly answer. What I get is just till 377 only. Didn't reach the 610. I ask Dr.Zul about it and he explained.

Then this is my first result :

My result.

Then the result.
