I think I had used a previous version of your code, I see that all graphics are sized for width and height of the size() function.Great, I’m so glad to hear that it worked for you and that the students had fun making it. which code should i modify?Through the Arduino, the Serial Communication and Processing IDE.sir dejan, i still blurred on the step.. can you please show me in detail? Thank you for putting up this wonderful tutorial!Please can u help me I got this problem “Error opening serial portCOM4:port not found” when I try to copilet, do u know the problem??

That sounds like a good project idea and you might be able to make it with this or similar sensor and setup. I tired to reduce the angle and at the end looked into increasing the serial baud rate which didn’t resulted in fast scanning. ?You can do that. Now we will try on a Windows machine. which software used for radar graphical display?The ultrasonic sensor u used for this project is HC- SR04. Thanks! ?You should adjust the screen resolution. ?thnx for the project it worked for me thnx again this is the video Hi, if i want to make the radar “full screen” how can i do? *; // imports library for serial communicationsir my processing shows a message could not load font OCRAExtended-30.vlw. This Arduino Radar Project is implemented with the help of Processing Application. Sorry for the lack of experience, I’m a student and I only currently have access to that model, and I would like to do this for a project. You are using an Arduino code in Processing IDE.I figured out what I was doing wrong and the project is working well.It might be done but you need to create your own code which wouldn’t be that simple.Well it depends whether the servo is driven in the same way as the mine.hello sir dejan, how do we connect the ultrasonic sensor with the laptop screen? Whenever I am using the CalculateDistance() function my servo motor starts to rotate slowly. It doesn’t move any where. Did you upload the Arduino sketch to Arduino properly, check if it’s working properly with the Serial Monitor. But also in the latest ‘complete source code’ bit, there is no #include and I am getting confused and I have already written half of the the code titled in red letters. Serial monitor always showed very same reading speed. My only trouble was finding out how to clear the font error in Processing but a quick google search taught me how to create the font. As for the Processing IDE part, make sure you use the last (latest) updated version of the code which is at the bottom of the post.Can some one please mention a download link for the above libraries for this project. I did “just because”, and it was very fun. I see that the code that you gave us is in 6 parts. can it be made that easily? You are probably not getting any value from the sensor. After replacing it, the project has been working perfectly now. In the Processing Sketch, make necessary changes in the COM Port selection and replace it with the COM Port number to which your Arduino is connected to.If you note the Processing Sketch, I have used the output display size as 1280×720 (assuming almost all computers now-a-days have a minimum resolution of 1366×768) and made calculation with respect to this resolution.In the future, I will upload a new Processing sketch where you can enter the desired resolution (like 1920×1080) and all the calculations will be automatically adjusted to this resolution.Now, run the sketch in the Processing and if everything goes well, a new Processing window opens up like the one shown below. Maximum is 32,256 bytes.Never mind the other comment, I figured it out and everything works fine now! I already have a tutorial on how to make your own custom Android application using the MIT App Inventor, so you can check it out and find some more details there.hi i just want to ask how can i match the distance of the detected object in the sonar since i already change the distance that the sensor to 1m, the distance that the sonar give doesnt match with the distance that the sensor detectis it possible to use the processing code to make it 360 and will it work with the existing arduino code?Well the servo motor can only rotate 180 degrees.
