Make this circuit on your breadboard first.

Then move it component by component to the circuit board, starting with the red wire which connects the power supply to the resistor. Attach the switch and the power supply last.

Be careful not to accidentally make wrong connections, and check your connections with the continuity detector in your multimeter.

When you are finished, the underside will look like this:

After you have tested everything, you can snip off the long ends with a wire cutter.
