JIN`s Fab Academy 2018:
How to make almost everything


week12: Output Devices


-group assignment-

measure the power consumption of an output device

1. MY RGB Board Design

I designed my own RGB board using eagle cad.
I realized that the design of the board was the same as that of Professor Neil, but the shape of the board was different.
So I made changes to the other side. In the case of the RGB Scheme, It was inverted and the power was changed in size.
But the final design did not work well, so I could not cut the board I designed.
Next, I will plan to DRC setting of Eaglecad again. Finally, I completed the RGB board. The RGB board is needed for my final project.

-My mistake-

I have not spent much time on Eaglecad, so I spent a lot of time designing RGB.
And the lead time was still short, so the copper wire was disconnected. So I modified it by using wires.


My final project appearance.

I made the design using Eaglecad. I reversed the RGB board.

I connected the line to each part.

However, I noticed that I made a mistake in schematic because I think it was very different from Professor Neil's RGB board.
So I painted a schematic again. And I changed R and B in rgb schematic because they are different locations.

The pinout diagram on attiny 45 shows the position of the RBG pin. Only one color can be adjusted with a pin.
The pin's application gives me adjustable information.

Finally, RGB board was completed.


I made boards with Roland. The cut was good and the soldering was done immediately.
But I made a mistake while soldering. So I used a wire to connect the lines. But it's well done !!

2. MY RGB Board sorderling and programming


I tried to upload but I couldn't because of the soliding problem. So I found the problem and then I tried to soldering again. Poor my RGB borad ...
Uploading was successful, but the RGB signal was not working properly, so I looked at the problem again.

So I finally connected the wires to fully upload and operate the RGB board.
I have recently uploaded file C from the terminal, not the upload using the Aduino IDE. I put Make file and C file in the folder and ran the terminal.
Enter make - f( file name )program - usbtiny. I succeeded in getting up.


This time, I changed the color and delay in the Aduino IDE and tried to code.
