A breadboard also known as protoboard is a type of solderless electronic circuit building.You can build a electronic circuit on a breadboard without any soldering ! Best of all it is reusable. It was designed by Ronald J Portugal of EI Instruments Inc. in 1971.
Building or prototyping circuits on a breadboard is also known as 'breadboarding '.In this instructable I will guide you how to use a modern breadboard to make simple circuits.
Step 1: Types of breadboard
There are various types of breadboard.Breadboard can be found in various sizes and functions.Early amateur radio hobbists used cutting board for bread to prototype there radios thus the name breadboard came.
Some breadboards got built-in powersupply,some got power supply rail and some got only the prototyping section.
