Networking and Communication"Check the reviewed one below" Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data. The Networking and Communications area focuses on the design and performance evaluation of communication systems and data networks of all kinds, including wireless/cellular, optical, ultra-low power, vehicular, mobile, wearable, data center networks, cyber physical systems, and the Internet. On this week i am going to make communication between two devices which is microcontroller and computer by using the serial communication.

about sensors that i have in my project its one called ultrasonic sensor the ultrasonic sensor by using the ultrasound as in input of my project.

In parts of programming

we can begin in programming of hardware

Here’s the Arduino Source Code with description of each line of the code:

Now we will receive the values for the angle and the distance measured by the sensor from the Arduino Board into the Processing IDE using the SerialEvent() function which reads the data from the Serial Port and we will put the values of the angle and the distance into the variables iAngle and iDistance. These variable will be used for drawing the radar, the lines, the detected objects and some of the text. by using java code.

For drawing the line that is moving along the radar I made this function drawLine(). Its center of rotation is set with the translate() function and using the line() function in which the iAngle variable is used the line is redrawn for each degree.

For drawing the detected objects I made this drawObject() function. It gets the distance from ultrasonic sensor, transforms it into pixels and in combination with the angle of the sensor draws the object on the radar.

All of these functions are called in the main draw() function which repeats all the time and draws the screen. Also here I am using this fill() function with 2 parameters for simulating motion blur and slow fade of the moving line.

that are the application interface that are created

that is the complete Processing Source Code of the Arduino Radar:

in part of electronics

we can begin to skech in software called eagle

we can convert the schematics that are design in eagle into to board.

conevert the board into the png in trace.

create the png of outline.

I have first converted my images from .png to .rml since its what the milling machine takes as input. I used fabmodules to convert fabISP images to rml. On Input format drop down I choosed image(.png), on output format I choosed Roland mill(.rml), and on process I choosed PCB traces(1/64). And continued selecting on machine I choosed SRM-20, other settings were made automatically then I clicked on Calculate button for converting it.

that schematics show some configuration by using fab modules

After calculation done on the image, the rml file is generated .

Now I have done the same thing on the edge cut file with some modification like on process I selected PCB outline(1/32) and on cut depth (mm): I entered 1.6 cause I want to cut through the board. .

After calculating the path for the tool the RML file is generated.

the final project.

All file used in that week we can Downloard here

we use the serial communication to communicate my project to my computer.
