Breadboard Complete

 First Breadboard circuit.

 LED ,1.0k ohm resistor , and 5V Power Supply previously created.

Building and Testing a 5V Power Supply

 The finished product after stripping the wires of the original power supply and using a soldering gun to solder the conductors to wires so I could proceed to test for polarity.
