UI Configuration Options

🖥️ Build/Load Arduino Sketch

1. Open Arduino IDE

2. Go to tools tab, and set your board, processor, and port

3. Go to file tab, and select open

4. Use the file explorer to select the tempReaderWriter.ino file

5. Hit the build/upload button in the Arduino IDE

6. Ensure your pins for you sensor match what is commented in the Arduino sketch

   1. GND
   2. PWR
   3. pin 2 is the data pin

7. Open Arduino serial monitor, and temperature, and humidity are being published

8. Ensure you close serial monitor, and any other applications that use serial communication with the Arduino before launching the GUI.

💻 Build Java Code

1. Install maven if you have not already

2. Ensure JAVA_HOME environment variable is set correctly.

   • windows: echo %JAVA_HOME%

   • Linux: echo $JAVA_HOME

3. Ensure that the maven bin directory is in your system path

4. 📂 Navigate to the unoTemp directory of the project in you terminal

5. run mvn clean install

6. If you get a build error complaining about the java version being 10 you can always adjust the target version in the pom.xml file.

   <plugin>
   	<groupId>org.apache.maven.plugins</groupId>
   	<artifactId>maven-compiler-plugin</artifactId>
   	<version>3.0</version>
   	<configuration>
   		<source>10</source>
   		<target>10</target>
   	</configuration>
   </plugin>

💻 ​Run/Setup Java Application

📂Navigate to target directory:

• target/unoTemp.jar is your application
• target/config.properties is your application config

💾 ​ Edit / save your configuration:

• Ensure you have selected your Arduinos port correctly, or the application will fail to display data.

• If you change the default colors make sure that they are provided as rgb values

  [0-255][0-255][0-255]

# Serial Port controller is on
serialPort=COM6

Run Application:

• Launch by double clicking in your explorer

• Alternatively you can launch from cmd/terminal

  java -jar unoTemp.jar
