6 Wiring DiagramA drawing meant to depict the electrical arrangement of the wires and the components they connect is called artwork or layout, physical design, or wiring diagram. Circuit diagrams are used for the design (circuit design), construction (such as PCB layout), and maintenance of electrical and electronic equipment.
8 Breadboard/Solderless Circuit The Breadboard allows you to build electronic circuits without having to solder parts together.PictureElectrical wiring diagram symbol
9 Jumper WiresUsed to connect components on your breadboard to make the circuits.
10 Electrical wiring diagram symbol Power SourceBattery stores electrical energy. The battery will have a positive & a negative terminal. In some circuits the ground is connected to the ground/body of the device.Example - in an automobile the ground is connected to the frame/body of the vehicle.PictureElectrical wiring diagram symbol
11 Electrical wiring diagram symbol Mechanical SwitchesThere are many types of mechanical switches.This is a on/off switch.It holds the circuit open(OFF) or closed(ON).PictureElectrical wiring diagram symbol
12 Electrical wiring diagram symbol Mechanical SwitchesThis is a momentary switch.On/off switch. It holds the circuit open and only closes the circuit while being held depressed.Limit Switch is just another type/name for a momentary switchPictureElectrical wiring diagram symbol
13 Electrical wiring diagram symbol Mechanical SwitchesThis is a two way switch.On/On switch. It holds the circuit closed in one of two circuit paths.PictureElectrical wiring diagram symbol
14 Electrical wiring diagram symbol Mechanical SwitchesThis is a three way switch.On/off/on switch. It holds the circuit closed in one of two circuit paths and closed in the other. Or, it opens both circuits at once.PictureElectrical wiring diagram symbol
15 Electrical wiring diagram symbol Fixed ResistorsIt resists current flow.Reduces electrical current.Color coded see chart belowPictureElectrical wiring diagram symbol
16 Fixed ResistorsDifferent physical sizes have different wattage ratings.
17 Electrical wiring diagram symbol PotentiometerVariable Resistor, as the wiper are moves across the resistive material it increases the length and therefore the resistance of the circuit.PictureElectrical wiring diagram symbol
18 Electrical wiring diagram symbol RheostatVariable Resistor, as the wiper are moves across the resistive material (a coil of wire) it increases the length and therefore the resistance of the circuit.PictureElectrical wiring diagram symbol
19 Electrical wiring diagram symbol PhotocellThis is a variable resistor / semiconductor that changes it’s resistance with the changing volumes of photons hitting its surface.PictureElectrical wiring diagram symbol
20 Electrical wiring diagram symbol CapacitorsThis is a device that stores energy, a temporary battery.There are different types.This is a Ceramic Capacitor.PictureElectrical wiring diagram symbol
21 Electrical wiring diagram symbol CapacitorsThis is a Electrolytic Capacitor.Danger! – Some capacitors have voltages that can shock and/or even kill.PictureElectrical wiring diagram symbol
22 Electrical wiring diagram symbol DiodeOne Way check valve.It only allows power to flow in one direction and stops it flowing the other way.PictureElectrical wiring diagram symbol
23 Light Emitting Diode (LED) This is a one way check valve/that also emits light.It only allows electrical current to flow in one direction.Arrow shows the direction of current flow.Note: LED’s in your kit cannot handle 9V, don’t hook them straight to battery!PictureElectrical wiring diagram symbol
24 Electrical wiring diagram symbol Transistor (PNP & NPN)It allows current to flow through it only after a small positive charge is applied at it’s gate.Used to amplify a circuit.Can store a (BIT) of data on/off, a 1 or a 0. So, enough transistors assembled together can create processor/memory.PictureElectrical wiring diagram symbol
25 Electrical wiring diagram symbol 555 TIMER (IC CHIP)Integrated Circuit (IC) – several components formed together on a silicon wafer: Transistor, Diodes, Resistors, Capacitors, and Etc.555 Timer very simple IC chip.PictureElectrical wiring diagram symbol
26 Silicone Controlled Rectifier (SCR) It is a Diode that can be turned off via a input signal on the third wire.So, Input a + charge on the third leg and the diode stops being a diode!PictureElectrical wiring diagram symbol
27 Electrical wiring diagram symbol SpeakerPictureProduces sound waves when a variable electric current is passed through it. It is type of “Linear Motor” that actuates the air.Made up of many component parts:Electrical wiring diagram symbol
28 Electrical wiring diagram symbol ELECTRIC MOTORUses electric magnets and stationary magnets to turn electrical energy into rotational mechanical energy.Note: motors in your kit are 3V, don’t hook straight to 9V battery!PictureElectrical wiring diagram symbol
29 ELECTRIC MOTORThere are many types and configurations of electric motors.All are going to have rotating magnet(s) and a shaft called a the Armature/Rotor.Stationary magnet(s) Stator.There are brushless types, however the one in your kit has brushes.
