WHY I AM RECEVING ERROR LIKE THIS my other freinds are able to run same code
why i am receiving error like this
1)Select your correct board of Arduino and then compile. it will compile perfectly.
2) analogWrite() works in arduino boards and pins are following :

I recently purchased the M5StickC Plus and wish to control computer cursor with it. However I'm having trouble compling the program.
Here is the error message when I installed the mouse library:
#include "HID.h"
^~~~~~~
compilation terminated.
Multiple libraries were found for "Mouse.h"
Used: C:\Users\Jerry\OneDrive\Documents\Arduino\libraries\Mouse
Not used: C:\Users\Jerry\AppData\Local\Arduino15\libraries\Mouse
exit status 1
If I uninstall the library it looks like this:
#include "HID.h"
^~~~~~~
compilation terminated.
exit status 1
What seems to be the problem here and how do I solve it?
The M5StickC Plus only provides serial communication via USB. It cannot emulate a USB HID.
You need an MCU that provides a real USB interface to run this example.
But you can implement a bluetooth mouse and keyboard if it's any comfort to you :)
I am using an Raspberry Pi Zero with an L298n motor driver to control two motors. I was testing the motors using a Python script. That worked fine.
Now I wanted to use the Arduino software to program the motors. I was following this tutorial on how to archive that: https://www.youtube.com/watch?v=lZvhtfUlY8Y
Then I coded this into the Arduino software (v. 1.8.5)
void setup() {
// put your setup code here, to run once:
Console.println("Setup Einstellungen");
pinMode(17, OUTPUT);
delay(500);
Console.println("Setup Einstellungen Ende");
}
void loop() {
Console.println("Rechts Vorwärts");
digitalWrite(17, HIGH);
delay(1000);
digitalWrite(17, LOW);
delay(5000);
}
I compiled the file using "Export compiled Binary". I uploaded it on the Raspberry using FileZilla and tried to run it via SSH.
When I tried to run it with:
(sudo) sketch_feb28.ino.bplus.bin
I got the following error:
: -bash: syntax error near unexpected token `sketch_feb28.ino.bplus.bin'
Running file sketch_feb28.ino.bplus.bin
sketch_feb28a.ino.bplus.bin: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SY SV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2 .0, BuildID[sha1]=a0260345a3700dca64c63fde8a10959214ce9b85, not stripped
I cannot solve this issue alone.
I'm still not sure, where the syntax error comes from.
Run the file with:
./sketch_feb28.ino.bplus.bin
This is the syntax for running a binary, that is not in PATH. Since the file is a valid executable, the error message should vanish.
I have built a matlab code with gui. It is connected to arduino. it works well on the matlab environment. but when i try to make a standalone program using deploytool, the program(gui) opens but it can not connect to arduino. matlab runtime is installed.
error messages:
Undefined function or variable 'registerrealtimecataloglocation'.

to connect to Arduino through matlab , needs
- com port of Arduino
- uart.. or baud rate
- matlab statement: serConn = serial('Arduino com port here', 'TimeOut', 1, 'BaudRate', 9600);
- fopen(serConn);
- str=char(fread(serConn));
str will receive data from Arduino in case if arduino print in serial any data
I am using Arduino and NetBeans in my project. My final work is to switch from Arduino program to Java. I managed to install an Arduino-NetBeans plugin as described in Arduino - NetBeans Plugin detail
My Arduino program includes
Serial.begin(9600); /////// Serial.print();
I get an error saying that "Unable to resolve identifier Serial". How can I solve this?
this is what you have to add to your source file:
#include <Arduino.h>
// imports the Serial class to allow log output
extern HardwareSerial Serial;
then it will work.
As answered by cgo you can add extern HardwareSerial Serial;
Or into your Project Settings, go to BUILD > C++ COMPILER > PREPROCESSOR DEFINITIONS and add: __AVR_ATmega328P__ (if you are working with Arduino UNO)
The message "unable to resolve identifier Serial" means that the compiler is searching for the variable Serial, but cannot find its declaration. You should check if you include all header files properly. I don't know the NetBeans plugin, but I guess the Serial-structure/class is initialised there.
If that is not helping, you should check the compiler otions and set them to default, as described on the project-site.
I hope this exact issue was not addressed already. I did search for a while.
So I'm using the Arduino library for Processing, testing it by simply having it blink an LED that I have connected to my Arduino UNO. I'm following this tutorial, but am having a problem a little different than the ones covered on that tutorial page. Here's my Processing code:
import processing.serial.*;
import cc.arduino.*;
Arduino arduino;
int ledPin = 13;
void setup()
{
//println(Arduino.list());
arduino = new Arduino(this, Arduino.list()[0], 57600); //error here
arduino.pinMode(ledPin, Arduino.OUTPUT);
}
void draw()
{
arduino.digitalWrite(ledPin, Arduino.HIGH);
delay(1000);
arduino.digitalWrite(ledPin, Arduino.LOW);
delay(1000);
}
Here's my error:
IllegalAccessError: tried to access class processing.core.PApplet$RegisteredMethods from class cc.arduino.Arduino$SerialProxy

Since my error apparently has to do with access permissions, I tried doing what it says at the tutorial page I was following by going to /var/lock folder, but the /lock folder doesn't exist! I'm using a Mac 10.8.2. I searched around and found this thread (arduino dot cc/forum/index.php?topic=135164.0) and decided to try "sudo mkdir -p /var/lock" and "sudo chmod 777 /var/lock" in terminal, but it didn't change the error I have in Processing, even after restarting it. I also tried opening the Arduino app and uploading the StandardFirmata sketch as mentioned at the ProcessngxArduino library download page (playground.arduino dot cc/interfacing/processing) while trying to run the processing sketch, but same error. The fact that I'm using the Arduino UNO instead of the Duemilanove shouldn't be the issue as the UNO is apparently just an updated version of it. Any ideas what I could try to do next?
UPDATE: Okay so the highlighted error in my code is what opens the serial port I'm using at whatever rate (57600 bits/sec in this case I think). So I think the problem lies in this particular step in the instructions at the adrunio x processing info page mentioned earlier(playground dot arduino dot cc/interfacing/processing), step 3: "Configure Processing for serial: processing dot org/reference/libraries/serial/"... the link goes to processing's 'serial' reference page. I'm confused about what is meant by "configure"? How exactly do I figure out my "correct serial port"? I went through the rest of the instructions and the examples on the serial reference page, and still have no idea what I'm looking for.
UPDATE #2: My serial port for the arduino is "/dev/tty.usbmodem1411". I am still confused about how to plug this in to my code in Processing though. The things I just learned in these last 2 updates might be irrelevant to my error, I'm still unsure.
The problem was that I was using the beta version of Processing (2.0). Use the latest stable version (1.5.1) and it should work.
