Breadboard Layout

Rows and Columns: The holes on the breadboard are arranged in rows and
columns. Components and wires can be inserted into these holes to create
circuits.

Power Rails: Long rows on the sides of the breadboard, usually marked with
a red (+) and blue (-) line. These are used to connect the power supply.

Connection Strips: The holes in the centre of the board are connected in
rows. When you insert a wire or component into a hole, it connects to everything else in that row.

Basic Components Used with Breadboards

Resistors: Control the flow of current in the circuit.

LEDs: Light up when current flows through them. Used as indicators.

Switches: Used to open or close circuits.

Wires: Connect different components on the breadboard.
