  • 8Section 1 ■ComponentsA 9-volt buzzer is shown in Figure L1-15.Two printed circuit boards are premade for yourprojects: Figure L1-16 shows the one that will beused for the night-light project; Figure L1-17shows the one that will be used for your SCRalarm project.Two adjustable resistors are also supplied: Thelight-dependent resistor (LDR) is shown in FigureL1-18 and the potentiometer is shown in FigureL1-19.Lesson 2Major EquipmentThe solderless breadboard and digital multimeterare two of the most common tools used inelectronics. Let’s introduce you to them now.The Solderless BreadboardWhen smart people come up with ideas, first theytest those ideas. They build a prototype. Theeasiest way to build prototypes and play with ideasin electronics is on the solderless breadboard,shown here in Figure L2-01.The main advantage of the solderlessbreadboard is the ability to exchange parts easilyand quickly.Figure L1-15Figure L1-16Figure L1-17Figure L1-18Figure L1-19
