Arduino Sketch Won Upload Programmer Is Not Responding
When programming the microcontroller using the Arduino ane tin come up across a number of errors peculiarly when compiling and uploading the lawmaking to the Arduino board. The compiling errors mostly include syntax errors whereas errors during uploading of the programme mainly include the connectivity issues of the Arduino board with the figurer to which it is connected. The compiler errors are mostly highlighted by the Arduino IDE and are easy to resolve but the errors that occur at the time of uploading the code to the Arduino board are difficult to resolve. So nosotros have discussed the error that is encountered past the users when uploading the code to the microcontroller.
What is avrdude: stk500_recv():programmer is not responding
To sympathize such errors first we take to know what is avrdude and for what purpose it is used in Arduino IDE. The avrdude is the utility tool used by the Arduino IDE for uploading the sketches/codes to the microcontroller board. So, from hither nosotros tin can suppose that this error might pop up when there is an result with uploading the code to the Arduino board.
When the mistake avrdude: stk500_recv():programmer is not responding arise
From the argument of the mistake we tin conspicuously run across that either the Arduino IDE and the Arduino lath are non connected with each other properly or both are unable to communicate with each other. In short, we can say that this error pops up when the Arduino IDE and the Arduino board are unable to communicate with each other properly.
This error mostly comes when we are using any communication device such as Bluetooth with Arduino that is using the TX and RX pins of the Arduino.
Why the error avrdude: stk500_recv():programmer is non responding arise
From the above discussion it is clear that this fault arises when there is a communication problem between the Arduino IDE and the Arduino lath because a communication device interfaced with Arduino is using its TX and RX pins. At present the question arises what is the reason behind such blazon of error. The reason backside this error is that when we upload the sketch to the Arduino lath using the USB cable the TX and RX pins of the Arduino boards are used and it can be seen that the LEDs of TX and RX blink at the time of uploading the lawmaking. Since the TX and RX pins are already being used by the communication device, the Arduino board does not reply to the data sent by the Arduino IDE and that is why this error arises.
How to resolve the fault avrdude: stk500_recv():programmer is not responding arise
To demonstrate how we can eliminate this communication mistake at the time of uploading the code we have interfaced the Bluetooth module with Arduino Uno and tried to upload the sketch. We get the same fault as you can run across from the epitome below and we have continued the TX and RX pin of Arduino with bluetooth:
Now to eliminate the mistake we take unplugged the TX and RX pins of the Bluetooth module from the Arduino lath as you lot tin can see in the image below so compiled the code.
Now yous can see in the figure that in that location is no error in uploading the code to the Arduino board.
Conclusion
Errors tin can exist expected while compiling the Arduino code in the Arduino IDE merely some of the errors are difficult to figure out. One of the errors which is difficult to figure out is the " programmer is not responding " error past the avrdude of the Arduino IDE compiler. We have discussed this error in item virtually what is this error, how this error is encountered and how we can solve this trouble in particular.
