Step 4: Fit Pin Headers
Because the I'm only using single sided strip board, we need to adjust the pins of the Pin Headers so they can be soldered to the strip board and still have sufficient pin length to make a good connection with the breadboard.
To do this you gentle push each pin through the plastic holding it until the end of the pin you're pushing is flush with the plastic. A small screwdriver is good for this.
Fit the adjusted pin headers to the strip board and solder them into place.
