 Bigger Bigger  Smaller Smaller  Reset Reset

i managed to load a new sketch by holding down the rest button and letting it go as the sketch size appeared

but i am still unable to open the serial monitor

it says the port is in use ?

problem fixed

i kept pluging the arduino in with the reset button down and letting it go just as it compiled before the write

eventually it started to work normally again

hope it is a one off !
