A breadboard is used to prototype a temporary circuit. The user can build, test and analyze a circuit without any permanent connections. It is made up of terminal strips and power rails. The terminal strips are used to hold any number of components in place and make electrical connections in a horizontal row. The power rails are the long vertical strips and are used to facilitate power (+) and ground (-) connections by placing them all in one column.

==== LED ====
A Light Emitting Diode, or LED, is a semiconductor device that lights up when an electric current passes through it. They come in many different colours and shapes, and are very versatile. LEDs are diodes, which means that current flows through the element in only one way, from the positive to the negative end. On an LED, the cathode end can be identified by either a flat edge on the body, or as the shorter leg. As such, the anode is the other end (the longer leg on the LED).
