• Complete all wiring connections as indicated in the sequence. After switching ON for a 

time period, motor will start to rotate. This delay is due to the charging of the capacitor. 

During the charging, the base electrode of the triode is in a low voltage so that the triode is shut. When the capacitor is 

charged fully, the triode is in its conducting condition, thus the motor will rotate. The time-delay period is the duration of the 

charging.

NOTE: Every time when you perform this experiment once, remember to “discharge” the capacitor before doing it again. 

Otherwise  it  won’t  work.  To  “discharge”,  connect  any  wire  to  72-73  for  a  second.  This  way  the  electricity  stored  in  the 

capacitor will be “discharged” and then the experiment can work again.

WARNING: 

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

components will get overheated.

• Complete  all  wiring  connections  as  indicated  in  the 

sequence. Switch on the main switch. Turn the variable 

resistor  from  the  minimum  to  the  maximum  settings. 

Adjust the variable resistor to a point which just will not 

trigger the color filter to rotate. This time, clap near the 

microphone, or blow to the microphone, or simply speak 

loudly will cause the color filter to rotate.

• Complete  all  wiring  connections  as  indicated  in  the 

sequence.  Switch  on  the  main  switch  and  touch  the 

touching-plate  with  your  finger.  The  circuit  will  be 

connected and motor will begin to rotate. If touching the 

touching-plate  does  not  show  anything,  dampen  your 

finger  with  water  before  touching  will  make  it  works. 

And remember to wipe the water off the touch plate after 

you remove your finger from it.

WARNING: 

Take away the color filter in this experiment.

Do not connect the color filter with the motor. Otherwise 

components will get overheated.

• Complete all wiring connections 

as  indicated  in  the  sequence. 

Switch  on  the  main  switch  and 

adjust the variable resistor slowly to a suitable position. 

LED  and  electric  motor  will  work  alternately.  The 

frequency of the alternation can be changed according 

to  the  adjusting  of  the  variable  resistor.    Adjusting  the 

variable resistor to its maximum, the electric motor will 

rotate  and  green  LED  will  extinguish.    Adjusting  the 

variable  resistor  to  its  minimum,  the  electric  motor  will 

stop and green LED will light up.

WARNING: 

Take away the color filter in this experiment.

Do not connect the color filter with the motor. Otherwise 

components will get overheated.

• Complete 

all 

wiring 

connections as indicated in 

the sequence. Switch on the 

main switch. Adjust the variable resistor slowly. This 

will change the control voltage of the triode, thus the 

speed  of  the  motor  will  change.  Utilizing  this 

principle can get a speed-adjustable electric motor.

WARNING:  Take  away  the  color  filter  in  this 

experiment. Do not connect the color filter with 

the  motor.  Otherwise  components  will  get 

overheated.

• Complete all wiring connections 

as  indicated  in  the  sequence.  

Switch on the main switch. Turn the variable resistor to 

minimum.  Red  LED  will  light  up  and  green  LED  will 

extinguish.  Turn  the  variable  resistor  to  maximum. 

Green LED will light up and red LED will extinguish. This 

principle  can  be  used  for  indicating  the  change  of 

direction of automobile, as different direction will cause 

different LED to light up and extinguish.

• Complete  all  wiring  connections 

as  indicated  in  the  sequence.  

Switch on the main switch. Drop a 

drop of water on the touch-plate, then red LED will light 

up and green LED will extinguish. Wipe the water off 

the touch-plate. Then green LED will light up and red LED 

will  extinguish.  This  principle  can  be  used  for  rain 

indicating  or  water-level  warning.  When  it  rains  or 

water-level  goes  beyond  warning  level,  red  LED  will 

light up, green LED will extinguish. Otherwise red LED 

will extinguish and green LED will light up.

• Complete all wiring connections 

as  indicated  in  the  sequence. 

Switch  on  the  main  switch. 

Green LED will light up while red LED will not. Shade the 

LDR a little bit, green LED will become dimmer. Shade 

the LDR a bit more, then green LED will extinguish and 

red LED will start to light dimly. When the LDR is covered 

completely, green LED will extinguish and red LED will 

light up completely. This principle can be used as light 

indicator, to reflect the amount of light shining on the 

indicator.

• Complete all wiring connections 

as  indicated  in  the  sequence. 

Switch  on  the  main  switch. 

Green LED will light up and red 

LED extinguish.  Press the push switch. Red LED will light 

up and green LED extinguish. This principle can be use 

for  indicating  the  break/connect  of  circuit:  When  the 

door, car-door or window is closed, this is just like the 

push switch is being pressed, and thus red LED lights up 

while green LED does not. When the door, car-door or 

window  is  opened,  this  is  just  like  the  push  switch  is 

released, and thus green LED lights up while red LED 

does not.

• Complete all wiring connections 

as  indicated  in  the  sequence. 

Switch on the main switch, then the motor will rotate. 

Now  cover  the  LRD  completely.  The  motor  will  stop 

rotating for a while. However, after keeping on covering 

the LDR for a time period, the motor will suddenly start to 

rotate again! If you uncover the LDR, then the motor will 

rotate  even  faster  for  a  while!  After  some  time,  the 

rotating speed will gradually back to normal. Cover the 

LDR again will stop the rotation again and the process 

mentioned above can be repeated. 

WARNING: 

Take  away  the  color  filter  in  this 

experiment.  Do  not  connect  the  color  filter  with  the 

motor. Otherwise components will get overheated.

• Complete 

all 

wiring 

connections as indicated in the 

sequence. Switch on the main switch, then after a while the 

motor will rotate. Access the reed switch with the magnetic 

pole. The rotation speed will be changed for a while, and 

gradually  back  to  the  original  rotation  speed.  Remove  the 

magnetic pole, and then the rotation will stop for a while. 

After waiting for some time, the rotation will resume again 

like it did at the beginning of the experiment! 

WARNING: 

Take  away  the  color  filter  in  this 

experiment.  Do  not  connect  the  color  filter  with  the 

motor. Otherwise components will get overheated.

the  rotation  speed  will  increase  for  a  while.  Do  not 

release  the  push  switch,  and  the  speed  will  gradually 

back to the original rotation speed. And then release the 

push  switch.  The  rotation  will  stop  for  a  while.  After 

waiting for some time, the rotation will resume again like 

it did at the beginning of the experiment! 

WARNING: 

Take away the color filter in this experiment.

• Complete 

all 

wiring 

connections as indicated in 
the sequence. Switch on the main switch. LED will light 
up. Then cover the LDR completely. LED will extinguish. 
Do not uncover the LDR and wait. After a while, LED will 
light  up  again!  And  then  if  you  uncover  the  LDR,  the 
statue will be just like the beginning of the experiment. 
You can repeat the experiment without switching off the 
main switch.

• Complete  all  wiring  connections  as  indicated  in  the 

sequence. Switch on the main switch. LED will light up. 

Use the magnetic pole to access the reed switch, and then 

remove the magnetic pole. LED will extinguish. Then wait 

for a time period, LED will light up again! You can repeat 

the experiment without switching off the main switch.

NOTE:  Every  time  when  you  perform  this  experiment 

once,  remember  to  “discharge”  the  capacitor  before 

doing it again. Otherwise it won’t work. To “discharge”, 

connect  any  wire  to  72-73  for  a  second.  This  way  the

• Complete 

all 

wiring 

connections as indicated in 
the sequence. Switch on the 
main switch and press the push switch. Electricity will 
flow through the triode so that LED will light up. At the 
same time the capacitor is being charged.  Release the 
push  switch.  The  triode  can  still  keep  conductive  for 
some  time,  as  the  capacitor  will  release  the  stored 
electricity. Therefore the LED will not extinguish immedi-
ately after you release the push switch.

• Complete 

all 

wiring 

connections as indicated in 
the  sequence.  Switch  on 
the main switch. Use the magnetic pole to access the 
reed switch. The circuit is connected and LED will light 
up. At the same time the capacitor is being charged.  
Remove  the  magnetic  pole.  The  triode  can  still  be 
conductive for some time, as the capacitor will release 
the  stored  electricity.  Therefore  the  LED  will  not 
extinguish immediately after you remove the magnetic 
pole.

• Complete 

all 

wiring 

connections as indicated in 

the sequence. Switch on the 

main switch. Touch the touch-plate with finger. You may 

have  to  dampen  your  finger  with  water  before 

touching. The circuit is then connected and electricity 

will flow through the triode so that LED will light up. At 

the  same  time  the  capacitor  is  being  charged.  Then 

remove your finger. Note that you may have to wipe 

the water off the touch-plate. You will see the triode can 

still keep conductive for some time as the capacitor will 

release the stored electricity. Therefore the LED will not 

extinguish  immediately  after  you  remove  your  finger 

from the touch-plate.

• Complete 

all 

wiring 

connections as indicated in 
the  sequence.  Switch  on 
the main switch. Cover the LDR completely, the LED will 
light up. Uncover the LDR and shine it with bright light. 
Then the LED will extinguish. This is because of the light 
falling on the LDR changes its resistance.

• Complete 

all 

wiring 

connections as indicated in 
the sequence. Switch on the 
main  switch.  LED  will  light  up.  Cover  the  LDR 
completely,  and  wait  for  some  time.  The  LED  will 
become dimmer and dimmer gradually. Finally it will 
extinguish. If you take away the cover thing, the LED 
will  light  up  immediately.  You  can  repeat  the 
experiment by covering the LDR again for some time.

• Complete 

all 

wiring 

connections as indicated in 
the sequence. Switch on the main switch. LED will light 
up. Cover the LDR completely, then LED will extinguish. 
Keep on covering the LDR for a while. After some time, 
the  LED  will  light  up  again!  If  you  want  to  repeat  the 
experiment, just cover the LDR again.
