hi
When i went to upload my sketch to the Arduino, i selected the wrong serial port and a current spike caused the Arduino to smoke.
When i plug in the USB cable, the red power light is on as well as the RX led flashing, when I just plug in the power cable the red light does not go on.
When i plug in the usb or power cable in the Arduino it does not smoke.
The Arduino still runs the sketch when powered by USB, as when I breath on the DHT11, the LED changes colour accordingly.
The only damage i can see to the board is that the voltage regulator has some melted plastic on top of it.
As it still performs its sketch properly, I assume that the only damaged component is the voltage regulator.
Will replacing the voltage regulator 'most likely' fix the board?
I can't take a picture because my ipads camera doesn't pick up the melted spot. Is there some kind of test that I can do on the voltage regulator using a multimeter to check if it is the problem?
I have tested with a multimeter and when the black power cable is plugged in, the voltage between the voltage in and voltage out is 12V so i presume the regulator is no longer working.
