For this keyboard, there are 5 rows and 17 columns. This means 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, place an inverter over each pin of the key switch and solder it. This will shield the pins of the key switch from current and also prevent them from being shorted. A diode permits current to only flow in only one direction. It comes with a visual indicator that is black, that shows the direction in which the current will flow.

The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks, which could ignite the gasoline that is in the engine compartment.
