The regulator is connected to a DC power plug, and the ground and voltage output of the regulator is connected to the voltage and ground bus rows on the right side of the breadboard. The ground and voltage bus rows on the right are connected to the ground and voltage bus rows on the left with wires at the bottom of the board. A pushbutton is mounted across the center of the breadboard, connected to rows 10 and 12. A 220-ohm resistor is connected to row twelve on the left side of the center section of the board. Its other end is connected to row sixteen in the center area. An LED is connected to another hole in row sixteen. The other side of the LED is connected to a hole in row seventeen.
