I just purchased my first Arduino Uno R3. however i am getting error message when trying to upload any code."avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00".. I have selected the board as Arduino uno and the port as /dev/cu.usbmodem101 Serial Port (USB) which both are correct for Mac. I dont have any additional wires on the board and I am trying with the simple blink test. The arduino has the on light and also pin 13 led light is on and stationary. When i try to upload any code the RX light also blinks but i still get the error message. any idea how can i navigate this? Thank you
usually new boards are preflashed with Blink sketch.
if you properly installed driver, then may be start IDE as admin.
Verify your USB cable is a data cable and not a power cable. Verify IDE >> TOOLS >> ARDUINO AVR BOARDS >> your board. Verify IDE >> TOOLS >> PORT >> your port
I think the mac is recognizing the device and the board and port selection are correct but i am still getting the error. Additionally, I purchased it just yesterday so I dont think its a faulty one. The LED light on pin 13 is constant and i keep on getting the same error
i dont have any other power cable. I am just using the USB to connect the arduino
my arduino uno has the ATMEGA328P processor so i dont know if this is new or old processor and i dont see the option to change the processor in Arduino IDE
try to reprogram amega328p over ISP
Does that mean I need another board?
or programer f.e. "USB ASP"
Does your computer make a "device inserted" tone when you insert your Arduino/USB cable? If so, that is a data (with power) USB cable. If not, that is a power-only USB cable.
Hopefully you have a friend you can take your board to and try to program it there. If successful great, if not you need a different cable. Try your friend's cable and see if that works, if so Update the blink sketch so it says something like: Serial.print("\nHello World"); and put it somewhere in the loop. In setup you need to add Serial.begin(115200); That is the baud rate. You need to set that on the terminal window on your machine. When you go home plug it in and the LED should blink and you should get a message on the screen with the Tx light blinking. I always put a hello message in my code followed by printing file: and Serial.print(FILE); Then when plugging in a board that has not been used for a while I validate the USB cable and know what code is in it.
I am a biology student trying to control the cooling rate of a water bath with this so I don't have any friends with electrical engineering knowledge. I have tried with the other USB cable and am still getting the same error message.
university in my town have 2 arduino boards, wanna be our student?
How? Which uni

That's not right if the board is a new board; it should blink. Where did you buy the board?
Based that I would send it straight back to the seller.
Do you get a couple of quick flashes on the L-LED when you press and release the reset button? If not, the bootloader is malfunctioning.
I'm not a Mac user. Does the port disappear when you disconnect the board?
the power on the LED light is always on while there is a faint light on pin 13 and it's not blinking. The light on RX blinks while I try the blink script but I still get the same error.
and i brought it from amazon
Amazon is big; a link to the exact product would be useful. And you did not answer all questions in post #16.

The LED on pin 13 ,there is no quick flashes. the light turns off when i am pressing the reset button and I have a faint light on when i release the reset button
