From morocco this is great bro, thank you so much

[@fyndssdev]

haha same, love from morocco!

[@sikkandar]

hello, your video is very helpful! can you tell me how you got the graph on the processing software. did you code in the arduino program?

[@mipoar7771]

Great content! What motor and type of blade did you use?? Thanks

[@paulabadie5897]

Fine job !

[@AnshAtulVirani]

Can you send the code of the graph you were plotting and also the list of electronics used for the same?

[@electronology4665]

Watch how I made the Wind Tunnel ! In Part 1: kzbin.info/www/bejne/faPWiYmVr6mSetE

You are amazing. keep going

[@paulhueber6718]

Whao very interesting 😳

[@electronology4665]

Ah yes indeed !

[@marouaneessahraoui6817]

please can u give me the name of that software u use in simulation?

[@electronology4665]

If you are talking about the software showing the graph, it is called Processing which you can download here: processing.org/download/ Here is the code I used: (you need to connect the arduino to the computer and Processing will collect that data) //Modified for a wind tunnel by Electronology // Graphing sketch // This program takes ASCII-encoded strings from the serial port at 9600 baud // and graphs them. It expects values in the range 0 to 1023, followed by a // newline, or newline and carriage return // created 20 Apr 2005 // updated 24 Nov 2015 // by Tom Igoe // This example code is in the public domain. import processing.serial.*; Serial myPort; // The serial port int xPos = 1; // horizontal position of the graph float inByte = 0; void setup () { // set the window size: size(1400, 800); // List all the available serial ports println(Serial.list()); // Open whatever port is the one you're using. myPort = new Serial(this, Serial.list()[0], 9600); // don't generate a serialEvent() unless you get a newline character: myPort.bufferUntil(' '); // set initial background: background(0); } void draw () { // draw the line: stroke(127, 34, 255); line(xPos, height, xPos, height - inByte); // at the edge of the screen, go back to the beginning: if (xPos >= width) { xPos = 0; background(0); } else { // increment the horizontal position: xPos++; } } void serialEvent (Serial myPort) { // get the ASCII string: String inString = myPort.readStringUntil(' '); if (inString != null) { // trim off any whitespace: inString = trim(inString); // convert to an int and map to the screen height: inByte = float(inString); println(inByte); inByte = map(inByte, 0, 60, 0, height); } }

@@electronology4665 Thank youu Sooo much broo, Merciiii

@@electronology4665 Thank you so much for the video. I had some problems with graphics and I need your help. When I run the software I get the following error and a blank non-working black graphical screen appears: "map(NaN, 0, 60, 800) called, which returns NaN (not a number)". Can you help me to overcome this problem? Thank you.

[@electronology4665]

That probably means the arduino isn't sending the correct data, for exemple, if it's sending text. Try printing the data from the arduino IDE and making sure it's numbers
