Connecting a battery to the circuit board; connect the red wire to to the red (positive) side of the power rail, and the black wire to the blue (negative) side of the power rail. You can put the red and black wires across both power rails, having power across the breadboard.
Rows are conductive and interconnected; if you plug in a wire to one of the five holes the entire row is connected. In order to connect each side need a jumper wire.
Jumper is wire is more versatile than a jumper cable.
Schematics can be read vertically, horizontally, or through a battery schematic (parallel vs. series).
Place the LED vertically. Connect a wire to the cathode of the LED and the negative (blue) side of the power supply.
Jump the gap with a resistor.
