Hello Experts!;
When I attempt to upload my sketch to the Arduino Pro-mini which has Atmega 328 processor,
I get this message: avrdude: stk500_getsync(): not in sync: resp=0x00
Anybody has experienced this? and found resolution?
Thanks,
Pierre
No. What USB to serial converter are you using? How have you got it wired up?
Like a Sparkfun FTDI BASIC . What voltage Pro-Mini ? (3.3V or 5V) ?

Have you chosen the correct board under tools-boards
?
That error will give you exactly that error message.
(I think quite a few other problems will give that error too)
How exactly did you connect the wires? Are the connections reliable? Did you try and switch RX and TX?
This is an extremely common difficulty, most often caused by attempting to do so using a "bodgie" (faulty design) USB to TTL converter using a CP2102.
In the meantime, the way to perform the upload is to hold the reset button on the Pro Mini as you start to compile the code in the IDE and release it the moment you see the "Uploading..." message in the broad blue bar at the bottom of the IDE window. It may take a little practice to get the timing right
