Introduction     

TRONEX – Connects to the circuit

We  take  pleasure  to  welcome  you  to  try  out  this  ready-to-use  electronic  circuit  kit 
suitable for children of 8 years old and up.  “You’ll be amazed” to find what you can 
learn  as  the  experiment  is  a  realistic  concept  of  electronics  and  electricity.    It  will 
definitely enable you to learn about the necessary electronic components, circuits, and 
theories  as  well  as  the  basic  electronics  principles  –  electricity,  voltage,  current, 
resistance, magnetism, other electrical circuit and theory.

It is alright if you have no knowledge about electronics and do not fully understand 
how all the experiments work. Once you get started you will be able to build your 
understanding  through  experimenting  and  maybe  trying  out  some  interesting
experiments on your own. 

This electronic circuit kit contains more than 72 experiments, and it is smartly designed 
that the main circuit board unit has all the relevant electronic components included.  All 
you have to do is simply connect the wires according to the wiring sequence of each 
experiment and follow the steps one by one.  Once connected the circuit will activate 
and function.

Remember  this  is  not  a  one-time  experiment.  The  more  you  spend  on  building  the 
experiments the better knowledge you will gain.  You will never get bored but totally 
engaged as you will discover more new exciting experiments for a few years to come.

Have a great electrifying experience !!!

WARNING: Only for use by children aged 8 years and older

WARNING

Adult supervision and assistance is required. 
This unit is only for use by children aged 8 years and older.
Not suitable for children under age 3 years old due to small part(s) 

and component(s) – CHOKING HAZARD.
Read and follow all instructions in the manual before use.
This toy contains small parts and functional sharp points on 

components. Keep away from children under age 3 years.
4 x 1.5V AA (LR6) size batteries are required (not included)
Please retain the information and this manual for future reference.

CAUTION !

Before setting up any experiment, please double check and make sure 

all wiring connections you have made are correct before inserting the 

batteries and switching on the unit as failure may result in damage to 

components or circuit board unit. 

When  experiment  is  finished,  make  sure  the  batteries  are 

disconnected and switch off the unit before you clear away the wires.

Do not apply any components or parts to the experiment other than 

those provided with this kit.

If this product malfunctions or "locks up", try switching off and back 

on again or removing and re-inserting batteries.

BATTERY INFORMATON

Use 4 x 1.5V AA (LR6) 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
Do not use rechargeable batteries
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

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 spring terminal 2 and 12. This is an example for 

reference only, not an exact circuit connection in the experiment. 
If the circuit does not work, you can check the wire and spring terminal 

connection whether it is not well connected or insulated plastic part of the 

wire is inserted to spring terminal.

EXPERIMENT

Color filter

• Complete  all  wiring  connections  as  indicated  in  the 

sequence.  By  switching  ON,  the  color  filter  will  be 

activated for rotating.

• Complete  all  wiring  connections  as  indicated  in  the 

sequence. By switching ON, the color filter will rotate, 

and red LED will light up; By switching OFF, the color 

filter will stop, and red LED will extinguish.

• Complete all wiring connections 

as indicated in the sequence. By 

switching ON, both red LED and green LED will light up. 

By switching OFF, both LED will extinguish.

• Complete all wiring connections 

as indicated in the sequence. By 

switching ON, green LED will light up, and the capacitor 

will  be  charged.  By  switching  OFF,  green  LED  will 

extinguish.  And  then  press  the  push  switch.  Capacitor 

will discharge to red LED and make it bright for a while. 

When  the  discharge  ends,  the  capacitor  has  used  up 

stored electricity and thus red LED will extinguish.

• Complete  all  wiring  connections  as  indicated  in  the 

sequence.  By  switching  ON,  LED  will  light  up.  By 

switching OFF, the LED will extinguish.

• Complete 

all 

wiring 

connections as indicated in 

the sequence. By switching ON, both red LED and large 

green  LED  will  light  up.  When  pressing  on  the  push 

switch, red LED will not light up, but large green LED will 

light up. This circuitry can be used for switching between 

weak light and strong light.

• Complete  all  wiring  connections  as  indicated  in  the  sequence.  By  switching  ON  and 

pressing  the  push  switch,  the  motor  will  rotate.  At  the  same  time,  the  capacitor  will  be 

charged. When the push switch is released, the circuit is disconnected, but the motor will still keep on rotating for a while. 

This is because the capacitor will discharge and release its stored electricity, thus the motor will still rotate for a while.

WARNING: 

Take  away  the  color  filter  in  this  experiment.  Do  not  connect  the  color  filter  with  the  motor.  Otherwise 

components will get overheated.
