Topic: Pin 10 is stuck HIGH (Read 359 times) previous topic - next topic

My Arduino mega (ATmega1280) has port 10 stuck on HIGH.  When I changed the code to use pin 9 it all works fine.  Is this common?  I assume I must have once made a wiring mistake and somehow burnt it out.

How do you know?

I tested it with a multi meter, set to DC volts.

After uploading an empty sketch to the board, you measure a stable 5 volts on pin 10?

Do you measure 5 volts after connecting a large value resistor (say 10K) between pin 10 and GND?

Did you remember to set the pin as an OUTPUT?
