I have got an arduino.I didn't know it's model number at first. Then, I saw the microprocessor. There it was written ATMEGA328P-PU. I am just a beginner and so i am trying out my first program with "blink". The compiler is giving me a message - "avrdude: stk500_recv(): programmer is not responding". I work on a linux mint system.
Thanks in advance.
Did you select the right COM port?
Do you know what Arduino you have?
Is it an original one with FTDI USB/serial chip or a clone with either: FTDI, CH340 or Prolific chip on board?
So check if you find one of those names on one of the chips close to the USB connector.
When you have identified the chip, google for the latest Linux driver for that chip, install, connect Arduino to your PC, select the right COM-port and you will be ready to upload the next sketch.
