I am in a bit of panic here, during some quite cramped testing, i didn't notice a screw that had rolled right bellow the 0 ,1 and 2 digital port of the arduino , and now i just can't transfer a program to it . :o -it is powered normally , (the testing led is still beeing lit as it was by the last program) -when first plugged in into the usb port : the rx and tx flash a few times :seems ok -at first the arduino ide recognizes the arduino's correct port, but as soon as i try to upload: wham ! port not there anymore and i get an "error opening serial port" error -during this upload attempts the tx and rx flash very fast, then just tx (stays lit on for a few secs) and then nothing
Any help at all , whether this is repairable or not, or if i can circumvent it (or , if as i fear, the serial port/chip or the whole arduino is simply dead) would be very appreciated!
Thanks in advance !
