In Chapter 5, we learned how a circuit works. However, the method of putting together a circuit in the chapter doesn’t translate to the real world well. In this chapter, we will learn how to use solderless breadboards to construct circuits in a more robust manner. Additionally, we will put our understanding of Ohm’s law to the test as we learn how to measure voltages in circuits using our multimeter.
A T-connector is just a cap on the battery that has wires coming out of it. If you don’t have a T-connector, you can manually plug a jumper wire into the breadboard and hold the other end on the battery terminal. T-connectors have their own drawbacks, as most of them have flexible ends, making them difficult to plug into breadboards. Shortly, we will move to an easier way of handling power with power regulators.
This can also be connected to a wall outlet using an appropriate adapter or connected to your laptop for a USB power supply. For the purposes of this book, we recommend against both of these options as it adds additional risk if something is wired incorrectly.
