7. Glossary
Amplifier - An electronic circuit that amplifies the signal that is sent to it. The amplifying component can
be a transistor, vacuum tube or appropriate magnetic device.
Battery - A source of energy. It contains chemicals which will undergo chemical reaction to produce
electricity when a circuit is connected.
Capacitance - A measurement of the capacity of a capacitor for storing electric charge.
Capacitor - A device consists of two conductors that are separated by an insulator. It is designed for
storing electrical charge or as a filter in a circuit.
IC (Integrated Circuit) - A small electronic device made of semiconductor material and is used for a
variety of devices, including microprocessors, electronic equipment and automobiles.
Light Sensor - There are different types of light sensor. The one used here is a phototransistor. When
light falls on it, it is like a switch connected and so current is allowed to pass through it.
Diode – A device used in electric circuitry to allow an electric current to flow in single direction and block
it in the reverse direction.
Microphone - A device converts sound into an electrical signal.
Motor – A device converts electrical energy to mechanical motion.
LED (Light Emitting Diode) - A diode emits light when current is passing through it.
Resistance - A measurement of the degree to which an object opposes an electric current through it.
Resistor - A device designed for possessing resistance.
Speaker - A device that changes electrical signals into sound.
Switch - A device for opening and closing power source to a circuit.
Transistor - A semi-conductor device that amplifies a signal and opens or closes a circuit.
Truth Table – It is a mathematical table used to logically compute the values of logical explication and
as a decision procedure.
Variable Resistor – A kind of resistor and a device of adjustable resistance in the electronic / electrical
circuit.
Wire - A conductor that conducts electricity. Connecting a wire is like providing a path that allows
electricity to flow though.
8. Battery Information
Use 2 x 1.5V AA size batteries (not included).
For best performance, always use fresh batteries and remove batteries when not in use.
Batteries must be inserted with the correct polarity.
Non-rechargeable batteries are not to be recharged.
Re-chargeable batteries are only to be charged under adult supervision.
Re-chargeable batteries are to be removed from the toy before being charged.
Different types of batteries or new and used batteries are not to be mixed.
Exhausted batteries are to be removed from the toy.
The supply terminals are not to be short-circuited.
Only batteries of the same or equivalent types are to be used.
Do not dispose of the batteries in fire.
Do not mix old and new batteries.
Do not mix alkaline, carbon zinc and re-chargeable batteries.
9. Wiring sequence and connection
Ensure all wires are correctly connected to the numbered spring terminals of the main circuit board unit
as stated wiring sequence of each experiment. Bend the spring terminal over and insert the exposed
