OBJECTIVE

- Add an output device to a microcontroller board you've designed and program it to do something.

Fabricate on of the "hello world" output examples board(s)

I put extra tin in my board's surface for recognizing it later (as you can see below).

PROGRAMMING

Program them (in as many languages as possible)

1. I downloaded the archives of the sensor I was going to build (RGB) in a New File inside my Desktop that I named "omar":

2. I opened the Terminal. I wrote cd Escritorio (Desktop in Spanish), then cd omar, next cd RGB in order to open and run the downloaded archives.

3. I wrote sudo make -f  hello.RGB.make program-usbtiny in order to run the C code of the RGB Output.

4. I connected  the Fab ISP and the RGB Output with the larger side from each of the 3x2 pins pointing in the same direction.

5. I connected the USB cable to the Fab ISP

6. I connected the 2x2 pins of the RGB Output to a battery

8. When I run the code, it appeared "Error 1". Therefore, I used the Multimeter to identify the problem and I realized that the circuits near the 2x2 pins that did not reach the regulator did not show a number between 8.9 and 9-1 in the Multimeter and the circuits that passed the regulator did not show a number between 4.9 and 5.1 in the Multimeter.

9. I changed the regulator and the Multimeter showed what I needed.

7. The code run!!!

8. The RGB Output was changing its colours, it was working!

PARTS & FUNCTIONS

GENERAL FUNCTION

Document what each board does, what protocol it uses, what you learned
- RGB SENSOR: Changes the color of a LED light to practically any color (all colors created by Red, Green and Blue light combinations)
- I learn that you need to check connections, when you start doing power electronics
- Each of this pixels contatins 3LEDs
-Regulator transforms 6V into 5V
- Power goes to processer
- Here a pin is selectevely ground
- Blue is less efficient; thus we need use more current
- The intensity varies by pulse in modulating (Faster than your eye can see it)
