A breadboard is a construction base for prototyping of electronics. Originally the word referred to a literal breadboard, a polished piece of wood used for slicing bread
A breadboard is commonly rated for five volts at one amp or fifteen volts at one-third of an amp, both of which have the power dissipation of five watts.
Because the solderless breadboard does not require soldering, it is reusable. This makes it easy to use for creating temporary prototypes and experimenting with circuit design. For this reason, solderless breadboards are also popular with students and in technological education. Older breadboard types did not have this property.
Another common use of breadboards is testing out new parts, such as Integrated circuits (ICs). When you are trying to figure out how a part, work and constantly rewiring things, you don’t want to have to solder your connections each time.
If you are working with a development board such as an Arduino, then you can simply pull power from the Arduino’s female headers. The Arduino has multiple powers and ground pins that you can connect to the power rails or other rows on a breadboard.
When using the breadboard power supply stick, make sure to insert the GND pins with the “–” rail and the VCC to the”+” rail. This will help reduce the chance of applying reverse polarity to your circuit.
