Uploading sketches to my arduino uno worked fine. Now uploading won't work. I get the following error. Is there a way to reset my board? Using the built-in reset button does not help. Error:
Arduino: 1.0.6 (Mac OS X), Board: "Arduino Uno" Binary sketch size: 7,878 bytes (of a 32,256 byte maximum) avrdude: stk500_recv(): programmer is not responding
Please give any information on how to fix or reset the board.
there are many reason and you need to try 2 or 3 different operations in order to understand why avrdude is not responding
First, check serial port on Arduino IDE, then check what kind of board you have selected in IDE.
Have you left some connected on pin 0 or 1 of your board? They are serial TX and RX used by FTDI to write the sketch on your Atmega, I don't know why but sometimes if you left something connected there, you could have some problems during upload.
Hope this will help you!

I have arduino atmega2560 when i upload blink code than it shows error
avrdude: stk500v2_ReceiveMessage(): timeout.
I have checked the COM port is correct also that the driver is correctly installed.
Why would I be receiving a timeout error?
The possible reasons:
Faulty communication cable
Wrong com port selected
Wrong device model selected
Baud rate settings
Driver related issues
I think your arduino got bricked. But first try to reconnect it and upload your program.
Second try to disconnect any rx or tx pin connected. Third if your arduino is bricked, try to check this article for full solution of bricked arduino. Programmer is not responding arduino
I'm trying to programm my PIC 16F628A with PICKIT3 in MPlabX, but I get the following error:
***************************************************** Connection Failed.
When I enable the "Power Target Circuit From Tool", I get another error:
The target circuit may require more power than the debug tool can provide. An external power supply might be necessary.
Connection Failed.
So a provided an external power supply of 5V and my PIC 16F628A is draining 10mA, despite nothing is connected, only the PICKIT3 to the MCLR, ICSPDATA and ICSPCLK pins of PIC.
I'm using Ubuntu 16.04, MPlabX IPE V4.05., and
PS: Yes, I know how to read a datasheet.
PS: Circuit and PICKIT3 works properlyt if I connect to PICKIT3 Programmer running on Windows 7.
The first issue can sometimes be resolved by shutting down MPLABX, disconnecting the PicKit from your computer and reconnecting everything. Seems the firmware and/or driver sometimes gets in a weird state and needs a good boot to get going again. I sometimes have to reboot my computer just to program my main board (Major PITA).
The second issue is not necessarily caused by an over current despite the message. I always got this error when my PicKit was plugged into an unpowered USB hub. It seems the lower USB bus voltage confuses the PicKit into thinking that the device is the cause for the voltage drop instead of the host simply not supplying the normal voltage. Try plugging it into a powered USB hub or directly into your computer.
I know this is an old topic but maybe this answer can help somebody else.
I use as well official PICKIT's as clones.
It could indeed be caused by a hardware issue.
E.g. short or already activated load like a bunch of LED's.
Disconnect all loads if possible.
When using an official PICKIT 3, this issue is often solved by setting the voltage your PICKIT should supply to a lower level e.g. 5 => 4.625.
In MPLAB go to the properties of your project.
Select PICKIT on the left.
Select Power from the selection dropdown at the top.
When you have a SURE electronics clone, this might do the trick. (Maybe this is also valid for other clones) The AMS1117 they used is the adjustable one.
They used a 680 and a 470 feedback resistor which gives a voltage of 3.09V ((680/470 +1))*1.25 + 50u * 680). If you swap the 680 Ohm resistor with a 750, the output will be closer to the probably desired 3.3V.

Close MPlab, reconnect Pickkit, restart MPlab worked for me.
If you've just created a new project or created a new file, MPlab sometimes confuses some things.
I have an Arduino Mega 2560. I want to make it communicate with Eclipse in order set a program on it. I have managed to work with Arduino Uno and Arduino Pro Mini until now.
With Arduino Mega 2560, though, I get the error shown on the photo below. I have used at the programmer "Arduino" , "STK500 v2" and "v1" at 57600 and at 115200. I get the error at the photo all the time with Arduino programmer. With STK500, I get an error that says:
Timeout while trying to access AVRdude programmer"
Is there a solution?
AVRdude emits a line like this:
avrdude: Device signature = 0x1e9702
which identifies the device, i.e. the exact type of chip it's connected to (the above is for the ATmega128). Your plug-in is probably not aware of the particular signature emitted for the ATmega2560.
It would be nice if you had included the GUI occluded by the error dialog, where the MCU type is configured ...
I have an issue with the WiFi shield. As you can see in the picture below, I am experimenting with the Arduino Mini and the WiFi shield.
I have read the tutorial-guide and connected all the necessary pins between the Mini and the shield. I use the example code which is provided in the tutorial, e.g. reading the WiFi shield's MAC-address or scanning for networks near me.
But anything I get is the error message, that the shield is not connected. But there is a connection between the two Pin 7's (the handshake pins) and even to any other required pin.
I even support my circuit with an additional power supply of 5V (the voltage regulator in the picture), so what's wrong with it? Or might it be that the WiFi shield itself is damaged or has a malfunction? How to verify this?
One last question is: Do they deliver the shield with an installed firmware or does the user have to install it?
The code I use is for example:
uint8_t wl_status = 0;
void setup()
{ // code to run once
// Open serial communications
Serial.begin(115200);
Serial.println("*** Arduino board online ***");
// check for the presence of the shield:
wl_status = WiFi.status();
if (wl_status == WL_NO_SHIELD)
{
Serial.println("-E- WiFi shield not present");
// don't continue:
//while(true);
}
else
{ // Initialize Wifi
Serial.println("-I- Initializing Wifi..");
printAddress(1);
// Scan for existing networks:
Serial.println("-I- Scanning available networks..");
listNetworks();
}
Serial.print("-D- Wifistatus : ");
Serial.print(wl_status, DEC);
Serial.println("");
}
The printAddress()-function simply prints out the MAC-address of the shield.
Have you tried removing the jumper? It puts the shield in programming mode. Picture here
I proved whether a different power source will work or not; the problem still remained.
Arduino support suggested that we should use the SPI connection of the board instead of wiring. It was worth a try, so I combined the WiFi-shield with an Arduino Uno and could finally start practising. Forget the Arduino Mini and use Uno or Mega instead.
According to the startup trouble, the current firmware version still has bugs, e.g. connection dies after a few seconds both on server side and client side. I recommend checking the Git repository frequently for updates. Issue #9 (Connection dies after a few seconds) has been solved on server side only, however the problem still exists on client side. I will wait for the next version of the firmware.
I have successfully talked to the computer from an Arduino via serial USB port and I had the idea that I could make a keyboard or mouse with the arduino. Say I wanted to translate the computer's mouse 1 pixel to the left. What message would I have to send over the serial line in order to achieve this?
Google is a wonderful thing. "use arduino as mouse" returns 1.7 million hits. The third hit on the list takes you to the Arduino Playground for an example using the new Leonardo board.
Note:
The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.
Assuming you don't have that board, here is another site for some other specific boards and yet another that is log for a project including hardware and software for older boards.
Hope this helps (and is a better answer to the question).
You would have to reconfigure the USB interface chip to appear as a USB HID endpoint.
