How To: Use a breadboard, also known as a protoboard

This two-part video introduces you to the breadboard, also called a protoboard, used to build electronic circuits without soldering. The first part of this presentation describes the features of a breadboard.

The second video continues by showing you how a breadboard is used to build electronic circuits without soldering, by guiding you through 10 steps to build a blinking LED circuit based on the 555 IC timer chip. The circuit also needs 3 resistors, 1k, 4.7k, and 10k. It also requires a 10 uF electrolytic capacitor, an LED, some jumper wires, and a 6-volt battery or power supply.
