A breadboard is used to build and test circuits quickly before finalizing any circuit design. The breadboard has many holes into which circuit components like ICs and resistors can be inserted. The holes are most commonly spaced 0.1“ apart to accommodate standard DIP components. A typical breadboard that includes top and bottom power distribution rails is shown below:
Figure 1 Solder-less breadboard
The breadboard has strips of metal sockets which run underneath the board, yellow rectangles in figure 2, and connect the groups of five holes on the board. The metal strips are arranged as shown below. Note that the top and bottom rows of holes are connected horizontally while the holes in the center sections are connected vertically.
Figure 2 Arrangement of internal connections
To use the bread board, the leads of components are inserted into the holes. Each set of holes connected by a metal strip underneath forms a node. A node is a point in a circuit where two or more components are connected. Connections between different components are made by inserting their leads in a common node. The long top and bottom row of holes, indicated by the red and blue stripes are usually used for power supply connections. The rest of the circuit is built by inserting components and connecting them together with jumper wires. Solid rather than stranded wire is the best to use with breadboards like these.
ICs are placed in the middle of the board so that half of the leads are on one side of the middle line and half on the other.
