Recently, I started a project using an Arduino Uno. I am using the Arduino IDE on macOS v12.2 (Monterey). The IDE was compiling and uploading to the Arduino fine; however, recently it still compiles, but keeps sending me the "programmer is not responding error" when uploading.
Below is my code and the steps I have taken to debug so far.
void setup() {
Serial.begin(1000);
delay(50);
}
void loop() {
Serial.print("Hello, World!");
delay(500);
}
First, I tried unplugging, replugging, and resetting my board.
I also made sure that the correct port and board were selected in the IDE.
Furthermore, I deleted the IDE completely and reinstalled it.
Lastly, I switched out the board and wire for other ones and the error still remained.
None of these seem to be the issue as I tested the same program and board on a Windows laptop and it uploaded fine. Additionally, the RX light flashes every couple of seconds and the L light is constantly on, showing proper connectivity. This leads me to believe that there is something wrong with the macOS and Arduino IDE specifically.

My new Arduino Uno Wifi, stops responding to wifi if left inactive. To be more specific, after 2-3 hours of no wifi usage:
I cannot access the build-in configuration page of the Arduino's wifi section
Loaded programs which use Wifi are not receiving any commands via my browser
loop() continues to run just fine
It somehow seems that the wifi section of my Uno Wifi "sleeps" after some arbitrary interval.
Using code to periodically reset the board (by sending HIGH to the reset pin of the board) did not solve the problem. As soon as the reset takes place, loop() starts executing just fine, but wifi connection is still impossible to obtain.
Things I usually do to gain access to my board AFTER wifi is lost:
Hard reset the board (unplug power and plug it again) -> almost always works
Try to access arduino from several different wifi devices hoping that the board somehow "wakes up" -> occasionally works but only after 4 or 5 minutes (sometimes hours) of failed attempts
My router seems to be fine. Another web server which I have set up in a wifi-connected laptop has had no hiccups (even after a long time of inactivity). Moreover I've never had any connection problems with my router so far.
This is giving me a hard time! Could anybody be of any help?
Is my Arduino Uno faulty?
Many thanks in advance
George
Here's my configuration:
Arduino Uno Wifi Developer edition (built-in wifi support)
Arduino IDE 1.8.0 (I'm using the Linux version installed on Ubuntu 12.04 )
I have already connected my arduino to my home network and gave it a static IP 192.168.2.50
WIFI mode: STA
Wifi channel: 1
SLIP status enabled
MQTT status disabled/disconnected
code:
int i=0;
void setup() {
pinMode(13,OUTPUT);
}
void loop() {
if (i==1){
digitalWrite(13, HIGH);
i=0;
}
else{
digitalWrite(13,LOW);
i=1;
}
delay(1000);
}
It seems that I have been a victim of an extreme ambiguity caused by the .org fork of arduino.
Arduino.cc and Arduino.org boards are NOT 100% compatible with each other.
To be more specific, the examples that come with the IDE (and are based on the the wifi shield of arduino.cc) DO NOT function with aruduino-uno-wifi (the one with the embedded wifi section)
Apart from that, it seems that arduino-uno-wifi has firmware that is way behind the arduino.cc (in terms of features as well as code quality). This has frustrated several users as you can see here:
Issue 2: Rename this fork and use less confusing versioning
Issue 10: Please stop doing this !
Issue 6: Remove old licenses from sample code comments and take credit for everything

The full story
All of the above is information which I wish I had when ordering my new ardnino-uno-wifi board.
Moreover it is relevant with the question I've asked, since it indicates that my problem is most probably a bug of the uno-wifi board, so I should file a bug report (and keep hoping) instead of trying to fix my code.
I am using Arduino Uno board and programming it with a Windows 10 system. From the tutorials on Arduino website, I am trying to upload the following code:
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
}
void loop() {
// put your main code here, to run repeatedly:
int sensorValue = analogRead(A0);
Serial.println(sensorValue);
delay(1);
}
It had undergone a series of issues:
First,
avrdude: ser_open(): can't open device "\\.\com3"
I searched for his issue, and found that most common solution is to go to device manager and change the name of the port, then unplug and plug again the arduino board. I did that
Second,
C:\Program Files (x86)\Arduino\hardware\tools\axr\bin\avr-ar:
unable to rename 'core.a'; reason: file exists\\
I thought it could be a memory problem. I used the reset button on the board, and repeated steps from the solution to the first problem. I tried to upload the code again.
But now, I am not getting any error message. But the problem is that it is taking forever to upload the code. I see Uploading... status since a long while. The green progress bar is also complete, but no uploading completed till now.
Any help to understand and solve this will be appreciated.
The solution for me was to disable Apple's Bonjour service with the task manager.
i got a brand new Teensy 3.2 with the blinking LED programm on it.
When I now tried to upload another programm on the teensy, Arduino says:
Teensy did not respond to a USB-based request to automatically reboot.
Please press the PROGRAM MODE BUTTON on your Teensy to upload your sketch.
The automatically starting window of Teensy, doesn't give me a chance to (for example) reboot the Teensy as well, so something of the connection seems to be wrong or something, but what...
Even if I mannualy press the pushbutton, it's still not possible to upload something. Any ideas why?
I have encountered this problem twice. The first I tossed out the board. This time, when I power it, it runs the last program I burned on it, but when I try to program it again, the LED stops blinking and everything stops.
The claim that it might not be a data cable is not reasonable, because how can it stop the current program unless it was told to. I doubt very much that +5V can provide such commands.
I have tried different cables, different USB ports, rebooting my Linux box, reinstalling (twice), checking the pins on the Teensy and the cable... no clue.
It always boots up in the old app (I left the blinker running to indicate "liveness"). I had programmed a message to come out the hardware serial port. Could that have been the problem? Wait... Is there a way to set the baud rate on the USB? I wonder if that is the problem! --
Banner(void) {
Serial.begin(9600);
Serial1.begin(115200);
};
The example had me programming the USB serial! I bet that is the problem! Better yet, does anyone know what the protocol is for talking to USB serial commander?
Under Ubuntu 18.04 install this https://www.pjrc.com/teensy/49-teensy.rules file into /etc/udev/rules.d
Existing Arduino project uses Arduino brand Duemilanove and Ethernet shield. It has worked well in operation for 4yrs (!) and then through a period of revisions I've been making just recently. I'm putting it back into service, but want to continue development, so have acquired an Uno board (with identical memory specs to Duemilanove), and a SparkFun Ethernet Shield.
I was able to program the new system fine for many revisions 20-30 times without problems - I'm aware of sync problems if you select the wrong board, so didn't have that problem.
Suddenly though, I get the error:
avrdude: stk500_getsync(): not in sync: resp=0x00
I checked the board selection of course, and it is fine. I even tried flipping it back and forth, and restarting the Arduino 1.0.5 IDE just in case, but I can't get sync anymore.
I've not being doing anything challenging with the code -just print statement edits and commenting the code.
HOWEVER - if I unplug the Ethernet Shield it works fine. Sync and load no problem. I can even replace the shield and the software works with the Ethernet still.
Why did it suddenly go south? Any thought if this is recoverable or should I just return the Sparkfun Shield as defective.
Thx for your input.
Ross.
I have been working with the Arduino system with an Arduino Uno chip for a while, but I recently came upon a problem I cannot solve. The problem is that whenever I attempt to upload a new program to my chip, I get the following error:
avrdude: stk500_getsync(): not in sync: resp=0x00
I have done some research, and I have tried everything that people have suggested. I have checked the COM port, checked the chip type, checked the component installations, updated the FTDI drivers, hit the reset button, tried the latest Arduino software, and yes, I have even made sure the board is plugged into the computer.
Earlier this year I had absolutely no problem uploading code to my board, and almost nothing has changed since I last tried it. The only thing that has changed is the cable I have used to upload the programs, and I have tried several different cables as well. Could it just be a batch of bad cables? This seems unlikely. I have also tried uploading code onto different boards, with the same result.
This is getting quite frustrating, as I really want to continue working on my projects. However, that will not happen if I cannot even print "Hello World!" to the serial monitor.
I am running on a 32-bit Windows 7 machine. Any suggestions to solving this would be greatly appreciated.
If you are expecting a normal upload using Serial then you should ensure your preferences are not set to "Upload using programmer" and that you are not selecting "Upload using programmer" from any of the Arduino menus.
EDIT
If you have not overridden the programmer then you must have the wrong board selected on the tools menu boards list. lpt1 in the error message is not what the Uno uses.
It turns out that the problem was the FTDI cable I was using. I tried a bunch of different cables until I found one that works, and now uploading occurs without any problems.
check the board you have selected in tools-> board . If you selected wrong board error comes as above. If right board being selected still getting same error , then it is definitely boot loader crashed error. You need to upload boot loader.
Sometimes parts connected to digital pin 0 and 1. The parts interfere communication between the computer and arduino so I recommend this procedure.
Check something is connected to D0 and D1.
If something is connected, unplug those.
Upload the sketch.
Plug parts removed at step 2.
your arduino maybe not uno, change board to duemilanove.
