How to Use a Breadboard

Purpose

A breadboard lets you make temporary circuits without soldering. On many full-size breadboards, groups of five holes on either side of the center gap are electrically connected, while power rails run along the edges.

Materials

Breadboard, low-voltage source, LED, suitable resistor and jumper wires.

Instructions

1. Identify the center gap and the row connections.
2. Disconnect power while inserting components.
3. Connect an LED with a current-limiting resistor in series, observing polarity.
4. Double-check wiring before applying an appropriate low voltage.

Do not connect household mains power to a breadboard. Follow your component datasheets and supervisor instructions.
