The next step is to wire the wires of the column and row to the microcontroller. This is the most challenging part of the project and requires a significant amount of soldering. There isn't a standard method to go about it, but you must determine how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.


After the rows and column are joined, it is time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current, preventing them from getting shorted. A diode can only allow the flow of current to be in one direction, and has a an indicator of black color that indicates which way the current will flow.

Don't connect the black cable to the negative terminal on the dead battery as this could cause an ignition spark that ignites the gasoline in the engine bay.
