So there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered, it's time to connect them to the key switches. To do this you must place a diode on each pin on the key switch and solder it. This will shield the pins from current and prevent them from being cut off. The diode allows current to only flow in one direction. It comes with a visual indicator with a black band that shows the direction in which the current will flow.
