using a light sensor to control LED light

Tried going to SIM LIM square to buy an audino to start fidgeting with it. Informed by the people there that it was a  fruitless trip.

spend time going through the source code for using a light sensor to determine the amount of light in the background and based on the analog reading to determine the amount of light the LED light should emit.

 int pin = 0 ;
int LEDpin = 9;

void setup()//working source code
{
 
  Serial.begin(9600);
  pinMode(LEDpin, OUTPUT);
}

void loop()
{
  int val = analogRead(pin);
  val = constrain(val, 750,950);
  int ledlevel = map(val,750,950,255,0);
  analogWrite(LEDpin,ledlevel) ;
 
}

Don't worry things will work out :)

Harvesting the Brainstorm - Project Arduino

After a session of brainstorming, we have looked at the different ways that a standard Arduino can help to improve or create functions in hardware items and have come to a consensus to have our Arduino software improve upon the functions of the camera with the help of a light sensor. Hence, our Project name shall also be known as Project Arditor, which is a word play on "Arduino" and "Editor" as we plan to make our resulting product an Arduino powered photography tool.

Being an amateur photographer, Ezra is consistently faced with the difficulty of getting the correct exposure value to get a picture taken of a particular scenery or object. He would have to resort to taking a few shots at the same thing then choosing the "best looking" picture via elimination.

This procedure is called Bracketing and it can be rather inconvenient and time consuming, not to mention that if the target object is moving, Bracketing will almost not work as the scene could change often, resulting in frequent changes to the lighting conditions.

As such, Sher Wen and Ezra had decided that the reason to execute Project Arditor is that such a helpful project will benefit majority of photographers or camera owners - helping them to capture clear and adequately lit pictures, especially during critical moments when pictures can only be taken during a limited time frame (Eg. moving objects/targets). 

At the end point, we aim to make Project Arditor, an USB compatible Arduino Motherboard coupled with Light sensor equipment, capable of adjusting the camera settings internally to allow the user to only have to zoom in or out of the object and capture a clear and adequately lit picture on the first try. We believe that this project will not be too complex to achieve and will hence achieve rather satisfactory results upon completion.

Future problems could possibly be that we will need to improve on our own coding/programming abilities to make our own goals for Project Arditor become a reality. 

The fact that Arduino is an open source software makes it quite easy for us to free make full use of its functions to make Project Arditor happen so quickly and economically in the first place. It could take us weeks and months just to get permissions from other software providers who will also charge us for the usage of their technology, making it much more costly for the end-user. We can carry on with the project without worry of any complications with the company we bought the Arduino software from. Also, the effects of pricing could also affect customer consumption as they might be deterred from using our product from Project Arditor. Thus an open source technology like this makes it easier for our product to reach our target users altogether, from the technical side to the political to the economical side. 

Naturally, our target users are basically anyone who owns a camera device. Almost every middle-income household and above would have a camera at home. As explained earlier, the product from Project Arditor is going to drastically reduce the need for a few things, namely Bracketing and even Photo-editing. It is foreseen to improve the overall quality of pictures taken by the user and also allow the user to enjoy the overall experience of photography, with less frustration from lighting issues. Pictures could be published much faster with much less photo-editing required.

The project might have potential to grow as an entire automated module in future camera models, possibly able to cover more than just adjustments due to light sensing but even colour scale recognition as well. Once again, open source technology of the software has given us the privilege to freely explore beyond the scope of the project. However, we are keeping the scope of Project Arditor to light sensing for now. 

In all earnest effort, we look forward to achieving great results from this project and learning experience :)

Below is a video on how photo-editing looks like. (A process our project aims skip or minimize for the end-user)

Different function of Arduino + Considerations during Brainstorming

Both Ezra and Sher Wen are tasked with going through different Youtube videos and see the multiple functions of Arduino and coming up with a function that we can propose our Arduino to serve.

Now we were faced with a number of questions with regards to the nature of the project we should partake in. 

This would mainly include: 

1. Why are we going through the particular project? 

2. Is the goal of the project achievable? 

3. What will be the potential problems we face - will the nature of the 
software being Open source be suited for us to reach our goals? 

4. Who are the targeted end-users and will it be useful to them? 

5. Do we have the time to complete the project? 

6. Will the project have any potential to grow in the long run? 

7. Whether it is worth the trouble of going through the entire project when other factors like personal handling skills or replacement of hardware would be more convenient?

In our team of 2, there is Sher Wen and Ezra.

We are called Arditor.

We hope to be successful this mod XD
