Breadboard
A breadboard is used for making solderless temporary connections using leads, which are pushed into the holes in the board to make connections.
This is basically a way of wiring a circuit temporarily, for testing purposes or to try out an idea. Since no soldering is done, all the components can be reused afterwards. it is easy to change connections and replace components.
Below is the external appearance of a breadboard. it has two rows of supply/ground channels on the
top and bottom, separated by two 5-hole vertical channel rows.
The conductor channels embedded under the holes if you rip open the breadboard from the bottom, you can easily see these conducting channels. all adjacent holes are separated by 2.54 mm (0.1 inch), enabling direct insertion of most iCs that have identical pin-to-pin spacing.
Normally, two sections of the breadboard are integrated into a single unit and are sold as a single breadboard.
