There are 22 microcontroller wires and pins that you can connect for this keyboard. It has 5 rows and 17 columns.

After the columns and rows are soldered, it's the time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins from current, preventing them from being shorted. The diode allows current to only flow in only one direction. It comes with a visual indicator, a black band, that shows which way current will flow.
