After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode on each key switch pin. This will protect the pins from current and prevent them from getting shorted. A diode allows current to only flow in only one direction. It comes with a visual indicator with a black band that indicates the direction in which current will flow.
