14_write an application that interfaces with an input &/or output device

This week, I will begin with the interface to work with my final project.

For now, the plan is to have a color sensor input, and a display with LED matrix output.

Adafruit_TCS34725
ControlP5
processing.serial
java.awt.datatransfer
java.awt.Toolkit

Here I share some screenshots of the interface.

And here the code:

Here’s a video demonstration.

_sql

Initial references:
SQLite
SQLite browser

Data management for use “SQLite” is a processing library, it is a database of local management, here the steps for implementation:

1. First, create a database, for this we use “SQLite browser”, it is a reader open for States database management code.

2. In the “SQLite browser” manage data entry and here we can add the parameters, here a screenshot with some sample data.

3. To connect the database, we need to place the database in the same folder as the processing code must be in a folder called “data”.

4. In the code, you must first load the library and define the name of the call, in this case.


de.bezier.data.sql import. *;
SQLite db;


5. To connect the database it is called a new base.

db = new SQLite (this, "RGBacteria.db");

6. To take the call to the database we will use the functions “if” and “while”..


if (test) {
statements
}

while (expression) {
statements
}

7. Finally to call a specific row and column we will use.

db.get "data type" ("position")

8. The full code.

import de.bezier.data.sql.*;
 SQLite db;

void setup()
 {
 size( 100, 100 );
 db = new SQLite( this, "RGBacteria.db" );
 if ( db.connect() )
 {
 db.query( "SELECT name as \"Name\" FROM SQLITE_MASTER where type=\"table\"" );
 while (db.next())
 {
 println( db.getString("Name") );
 }
 db.query( "SELECT * FROM table_one" );
 while (db.next())
 {
 println( db.getString("field_one") );
 println( db.getString("M03") );
 }
 }
 }

Here’s a video demonstration.

_conclusions

This activity develops the first draft to the final draft interface, the general idea is to the graphical representation that will help reading physics bacteria, in the part of the learned programming color sensor connection, data management SQL and use graphical interface for libraries.

I think the interface is an important part of the project, the end is how the processes communicate with the device and how to manage them.
