board reset

good day!
i have a problem w my duemilnov board. the last led 3x3x3 sketch that i have made still runs whenever i plug the board to my computer. I already made a different sketch on a 4x4 but still the sketch for the 3x3 runs eventhough i have pressed the reset button, why is that? tnx

why is that?

Sounds like you didn't actually upload the new sketch to the Arduino.

dinky:
eventhough i have pressed the reset button, why is that?

The RESET button restarts the microcontroller. It doesn't do anything with the code in Flash memory.

Maybe an error is occurring on upload, so the code isn't actually changing.
