How to delete code on Arduino board

I want to delete code on Arduino board. How to do it? How to clear the sketch in a Arduino? How to erase Arduino sketch?


You can delete the existing code on Arduino board by uploading the bare minimum code to Arduino.

void setup() { } void loop() { }

After uploading the above code to Arduino board, the Arduino board do nothing, just like there is no code on Arduino board.
