I bought a second uno and my program does not syc with it , I changed the delays of the blink sketch and it gives an error code. it tells me" stk500_getsync(): not in sync: resp=0x30" I know it in the comm port but i only see one comm port under tools>serial port. What did I do wrong? Charlie J
This example code is in the public domain.
*/
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(3000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(3000); // wait for a second
}

Re: issues with new uno board
Hi Charlie,
The sync error is not related to any change you made to your sketch. It is usually due to a communication problem between your computer and the UNO. Since it is a new board, the computer probably assigned it to a different COM port. Make sure that you have that COM port selected in "Tools->Board Type".

Re: issues with new uno board
I looked over the info and decided to reload the drivers. I had gotten the uno rev3 board and I guess its a little different so it needed a new driver. also I noticed a couple of extra pins in the headers, I have not looked at the web site for answers so what are they for? thanks Charlie J

Re: issues with new uno board
The extra pins are for compatibility with the Mega. They are duplicates of other pins on the header, so the R3 is still backwards compatible with the older UNO.
