What have you got connected to what board, and where did you get the board from?
Have you got the right drivers for the board?
I have the correct drivers install, i had loaded some programs before to my arduino
My OS is Windows 7, The newest IDE 1.6 i just installed it. The board has nothing connected to it. Its driving me crazy
I was searching in previous posts and found one of a guy having the same problem and solve it by changing the COM#, i've done that and still dosent works
The Arduino output pins basically can give you 20 mA. That probably isn't enough to operate a relay. The absence of flyback diodes probably means the high voltages (that the diodes are designed to stop) damaged your CPU.
Hi there, im having some troubles with my Arduino Uno. Each time i want to load a programm it keeps sending me an error:
avrdude: stk500_getsync(): not in sync: resp=0x30
I have read some, and it say that this error occurs because some trouble communication with the Arduino and the PC, but i have previously loaded some programms with no trouble.
I've tried to do the Loop back Test but no success because the same problem
in my case this error was referring to wrong/ none COM port selected.
Also if you use arduino mini pro and ttl programmer without autoreset pin you can see this error if you didnt press reset button right before uploading code to the board.

Im using arduino uno r3 with Windows 7, and i've tried assigning a new port but still with no luck :l
