I made a sketch with just a delay in loop(). setup() is empty.
5.11 VDC with nothing connected. 1.74v with an LED and resistor.
The other digital pins read 0
Is there anyway to read what those resistors are set to? I've just gotten mine and have not fully learned the language or capabilities yet.
Ok, I learned how to reprogram the pin and it reads 0. It would be a bit annoying as I don't see a way to set the pin back to an output after having to set it to an input to set that resistor off.
Anyone else tried this - I'm looking for a little more data to confirm that this problem is in the official bootloader/hardware distribution.
Send Arduino a blank sketch. The sketch can do anything else, but shouldn't do anything to pins 0 to 7.
Put a voltmeter between pin 6 and ground to cofirm whether it's at 5 volts.

void loop() // run over and over again
delay(1000); // waits for a second
