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.
Reed-switch: This is a magnetic switch which contains metal reeds inside. When a magnet is close to it,
the attractive force will cause the reeds to come together. Thus they will be in contact and the path is
connected
Touch plate: It is a plate with two parts of conducting surfaces. The two surfaces are not connected but
with a little gap between them. Electricity cannot flow through because of the little gap. When touched by
a finger, or dripped with a water droplet, then the little gap is filled and electricity can flow through it
(though the resistance is quite large because the resistance of water is quite large)
Buzzer: A device that can produce simple sound
SCR: A silicon-controlled rectifier, or SCR, is like a traffic cop for electricity in electronic devices. It
allows the flow of electricity in one direction, acting like a gate that opens and closes. It's a special kind
of switch that helps control the power and make sure everything runs smoothly.

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.
To insert batteries please unscrew battery cover with a screw driver. Insert the required batteries in
accordance with battery polarity with + and – ends in the right position and then fix screw on the battery
cover to close the battery compartment case.

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
shiny conductor part of wire into spring terminal. Make sure the wire is securely connected to spring
terminal.
For example if the wiring sequence is 4-33, 1-10-32-35, 2-12, then connect a wire between spring
terminal 4 and 33; and then connect a wire between spring terminal 1 and 10, and a wire between spring
terminal 10 and 32, and a wire between spring terminal 32 and 35; and finally connect a wire between
