installations and program running


I have recently purchased the arduino uno kit and I was running a simple program to get started and in to the work from the manual program saved alright but didn't upload ie., the blink program,

constantly getting back

avrdude : stk500_getsync(): resp=0x30

coming back when I am uploading

also I would like to know how the serial monitor works


For the serial monitor, search for "Serial.print" and you will get plenty on the use of the terminal.

This is the generic message saying that the IDE isn't able to send the program to the Arduino.

1) Could be the wrong board selected. 2) Could be a bad cable. 3) Could be a bad (or missing) boot loader.
