Output devices
This week we learned, in order to have a better controlled systems and improved experiences, about a series of peripherials to produce desired effects within programming.
Every device has a specific range of action, and in my particular case, i wanted to explore the Servo motor and the TCS3200 Color sensor with the LCD screen.

Research:
As far as we know, i haven't been able to access a roland milling machine, however with the supplies at reach, i tried to create some ideas.
Looking at the examples were posted on the Fab Academy page, i realize that simplicity is paramount, and trying new things with known objects is quite an interesting feature.
Programming
I'm using the Arduino desktop app to ensure communication and programming, i know that is slightly different way to express the code, and it has been a good way to keep learning.
I used a simple code to make a run with the color sensor, and see what hhapened, however, i realized that i had no feedback without the computer, so i created a second excercise.
Programming 2
With this exercise, i realized that i could bring a data directly to the LCD screen without being attached to the computer, so i defined the pins and ports to have the proper communication in-between the programer and the board.
This thing might help me with my final project, to identify beyond light and try to "see" the colors and create a mood.
Programming 3
Then i tried to use the Servo motor to test two things, the ultrasonic sensor, so it could create a responsive twist with human approach, however, the slow motion response wouldn't show the real effect of the servo, anyway it showed a little idea of what is to see the engine working with the distance from the user.
Programming 4
Finally, using the base code from the previous excercise, i tried a diffrent thing, why not, create a "chart" using the servo motor as a pointer with the ultrasonic sensor, to measure the proximity as a dial... process that is a little bit more interesting and fun.
Rework...
I managed to re-create with a simple board the basic PCB functions to see if that end up working with the LCD.
I had the chance to manufacture it and then program the pcb.
Just to check for the final project.
Conclusion
These week let me understand a lot more about programming concepts, the order of the writing, the language, and the connectivity in-between devices.
I finally have the chance to produce my own board and program them for my final project... it worked fine.
