I am not able to successfully load programs to my arduino. Apparently there is a bootloader on the chip because when I plug it in (usb) a small led blinks near the 14 pin. However, when I plugin an led in the 13 and grnd it does not blink. Does this mean that there is a problem with the bootlader that the arduino shipped with? I had wanted to use this in an installation with range finders communicating with Max/MSP.
