Pierre's 170W in 1600W out Looped Very impressive Build continued & moderated

Yeah, it's just the port by the looks of it.
Nothing wrong with the code.
At the bottom of your screen it shows you've selected the right type of Arduino and indeed it compiles fine. The only thing different would be the Port.
Click 'Tools', then 'Port' and see what it says there...you should only have 1 or 2 to select from and it seems like it's picking the wrong one as default.

Another way, is to unplug the Arduino USB cable and plug it back in, the other port will then be selected. At least here on Linux Mint it does, from USB0 to USB1 even if it's the same device being plugged in and out.

I had a similar problem,  but by installing the "driver" and reinstall of the complete Arduino program resolved identifying the port connection identification... : ]

Might look into that.
It's worthwhile pointing out because of easily understood frustrations for new folks.

Well, it looks like the Arduino board itself has a communication issue. The program is working but I can't upload any changes. See video.
So if someone can send me or buy me a replacement that would be great. Meanwhile I can test as is and need to know if I add a potentiometer (to vary frequency) is that part still in the program?

Fr. Eh bien, il semble que la carte Arduino elle-même a un problème de communication. Le programme fonctionne, mais je ne peux pas télécharger de modifications. Voir la vidéo
Donc si quelqu'un peut m'envoyer ou m'acheter un remplacement ce serait génial. En attendant je peux tester tel quel et j'ai besoin de savoir si j'ajoute un potentiomètre (pour faire varier la fréquence) cette partie est-elle encore dans le programme?

One more thing you should check is the serial port baud rate. You can change this under the device manager in Windows. I am not sure what the rate should be for the Arduino, but try the following rates:

9600, 14400, 19200, 28800, 38400, 57600, or 115200

For the potentiometer, you can uncomment Pierre's old lines:



int y= analogRead(0); // transforme x en une valeur de 0 à 20 (millisecondes)
x= map(y,0,1000 ,1,100);

and then comment your x=50 line:
// x=5; //total loop delay is 20*x = 100ms. f=10Hz


The potentiometer has 3 leads. Two outer ones should be hooked up to GND and 5V and the center one should be hooked up to the analog 0 input.

Options;
1). Remove board / UN-plug completely from device and re-program.

2).Add the following to the sketch....

void setup() {
  // initialize serial communications at 9600 bps:
  Serial.begin(9600);
}


It initializes the serial connection at 9600 bits per second. Both sides of the serial connection (i.e. the Arduino and your computer) need to be set to use the same speed serial connection in order to get any sort of intelligible data. If there's a mismatch between what the two systems think the speed is then the data will be garbled.

9600 bits per second is the default for the Arduino, and is perfectly adequate for the majority of users, but you could change it to other speeds: Serial.begin(57600) would set the Arduino to transmit at 57600 bits per second. You'd need to set whatever software you're using on your computer (like the Arduino IDE's serial monitor) to the same speed in order to see the data being sent.

3) Looks like board is running when you re-programed, which is fine,  that can be done,  however Pierre may have been correct in pointing out the "field" may interfere with the board ?

That's all I have to comment... : {
