I'm working with Arduino Due and I have a sensor that outputs a square signal with voltages in the range of 0-5V.
In the Due specs there is a warning that says:
"Warning: Unlike other Arduino boards, the Arduino Due board runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Providing higher voltages, like 5V to an I/O pin could damage the board."
Is it possible to connect it to the board?
