The Arduino Mega's pins are vulnerable to voltage spikes and other forms of electrical stress, which can cause permanent damage. To prevent this, users can implement pin protection using resistors or diodes. This can be achieved by placing a resistor in series with each pin, or by installing a diode across each pin. The diode will allow current to flow into the board, but block it from flowing out, thereby protecting the pins from voltage spikes and other forms of electrical stress.
