Breadboards are prototyping tools used to build electronic circuits. Users can make connections and build circuits that perform a variety of tasks. Beginner breadboard projects use a variety of components to makes sounds, blink LEDs, build sensors and can be powered by a 6V battery.
It’s easy to get started. Breadboard kits with a standard set of components are cheap and readily available. Plenty of projects have step-by-step instructions free on the internet.
