Thank you very much for your reply.
In response to your questions:
My September 26, 2014 post was my first. I have no prior experience working with electronics or with Arduino.
So far, I have downloaded the Arduino software and installed the Arduino Uno drivers. I have run the blink example sample successfully on a mini HP using Windows 7.
I am doing this project for science fair as a continuation of the project I did last year on camouflage fabric. This year, I would like to improve my prototype by making the camouflage active, using the color detector sensor and the fading RGB LEDs. The Oct. 20 deadline is set by my teacher, where the research paper and project board must be completed by that date. Unfortunately, I just found out my project was approved yesterday. Today is my official start date. This project is for a regional science and engineering fair.
I thought I would need an RTC if I wanted to test colors outside versus on a computer monitor. I thought it would be important to have the time stamp associated with the data, assuming that colors and RGB values change with the light intensity in the course of a day.
Sorry about the "data logger" term. I have an Open Log. Again, since I need to tabulate and collect data for my experiment, I thought I would need this component. I am hoping to extract some of the information from the Open Log as my data.
The link for the color detector sensor data sheet is:
There is no datasheet for the fiber optic fabric. It is manufactured by Sensingtex. Basically, the fiber optics are woven into the fabric where they are terminated in a bundle at one end and secured by a metal collar. An LED can illuminate the fabric by inserting the led in the metal collar and sealing it with a tube of heat shrink.
I will do the homework you assigned and post again when I have completed it. I would have done the fading led tonight, but I have 330 Ohm resistors, not 220 Ohm resistors that are listed on the arduino website. Since I know nothing about electronics, I didn't know if using a higher resistance would do any damage to the Uno.
For #3 of the homework you mentioned getting a SD Shield. Can I collect the data from the Open Log and save it onto my computer? Does the computer act as a serial monitor?
I am not asking for anyone to do my project for me. I know what I want to accomplish, but I'm not sure where to start or how to get there. Ideally, it would have been helpful to have a mentor guide me through the process. Normally, I would have more time to work on this project. However, our teacher has given us a very tight timeline. Therefore, I truly appreciate your guidance and expertise in helping me acquire some electronic skills and knowledge while achieving my goal.
Thank you for your time!
