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 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 a wire is inserted to spring terminal.

10. Component characteristic

In this experiment kit, you will learn basic circuit theory, characteristic of capacitor, IC (Integrated Circuit), LED (Light Emitting Diode), light sensor, resistor and transistor. You can learn that when transistor and capacitor work together, various light and sound effects can be made in different circuit connections.

Capacitor is 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. It is a commonly used component in electronic and electrical circuits as an energy storage device or as a filter device to filter out electronic noisy or useless frequency signals. There are various types of capacitor which are designed for different electronic / electrical circuit applications.

IC (Integrated Circuit) is a small electronic device made of semiconductors and is used for a variety of devices, including microprocessors, electronic equipment and automobiles. IC is made by a large number of transistors into a "chip" (silicon). It is now a critical and commonly used component in a wide variety of applications from toys, household products to state-of-the-art equipment.

Light Sensor is a device that reacts to light. There are different types of light sensor. The one used here is a phototransistor. When there is no light, electric current cannot pass through it. And therefore it is like a switch that is switched off. When there is light falling on it, electric current can pass through it. It is then like a switch that is switched on. This way a light control circuit can be made.

User manual

The motor is a device that produces rotary motion when electricity is provided. As an analogy, the battery is like a pump that pumps water through the piles (wires). When a circuit is connected, electricity can flow through it. The electricity flowing is called a current. A current is the flow of electric charges. The amount of a current is the amount of electric charge flowing in the wire in a second. Another common term we often heard about electricity is the voltage. Voltage is referring to the electric energy per unit charge. It is the electric energy of each unit amount of electric charge carries.

• When you press the push switch, the yellow LED will light up. Release the push switch so that the yellow LED will be turned off.
• Now switch off the main switch. The red LED will extinguish. If you press the push switch at this time, the yellow LED will light up for a brief moment due to the release of the stored electrical charge of the capacitor. However the red LED will not light up at all because the diode has blocked the current from the capacitor which is in an opposite direction.

12.16 EXPERIMENT 16 - A simple demonstration of the light sensor

Wiring Sequence

2-34, 33-16, 15-13, 14-1

2 1 14 13 34 33 16 15

- Complete all wiring connections as indicated in the sequence.

- Switch on the main switch. You may notice that the LED lights up very dimly. This indicates only a very small amount of current is flowing through it. It depends on the intensity of light falling onto the light sensor. If you perform this experiment in a darker place, the LED may not light up at all.

- If you use a torch to shine on the light sensor, you can see that the LED light up brightly. This is because when there is more light, more current will be able to pass through the light sensor and light up the LED.

12.17 EXPERIMENT 17 – A simple demonstration of a function of the PNP transistor

Wiring Sequence

2-7, 9-16, 8-34, 33-15-13, 14-1

34 33 8 9 7 2 1 14 13 16 15

- Complete all wiring connections as indicated in the sequence.

- Switch on the main switch. This time, even with a small amount of light, the LED will light up brightly!

- It is because in this circuit, the PNP transistor is the real gateway to the LED, and the light sensor is only acting as a switch for opening the gateway! When the upper part of the circuit is not connected, no current is flowing through the "Emitter" to the "Base" of the transistor. So the gateway of the "Emitter" to the "Collector" is shut. When light falls on the light sensor, the upper circuit is connected; a very small amount of current passes through the "Emitter" to the "Base", and then the gateway of the "Emitter" to the "Collector" is opened! Electric current from the battery can then flow through the transistor to the LED, and therefore the LED will light up brightly! This circuit makes the light sensor to become a sensitive switch to detect light.

12.18 EXPERIMENT 18 - A simple demonstration of a function of the NPN transistor

Wiring Sequence

2-34-16, 15-12, 11-33, 10-13, 14-1

• Complete all wiring connections as indicated in the sequence.
• Switch on the main switch. Again, this time even with a small amount of light, the LED will light up brightly!
• This is pretty much the same as the case of the PNP transistor. It is just the polarities of the transistor that are reversed.

12.19 EXPERIMENT 19 - Delayed lighting up LED

• Complete all wiring connections as indicated in the sequence.
• Switch on the main switch. Because of the capacitor, the LED will not light up immediately. The LED will light up after a while.

NOTE: If the experiment does not work, you may need to "discharge" the capacitor first. To "discharge", connect any wire to 21-22 for a second. This way the electricity stored in the capacitor will be "discharged" and then the experiment can work again.

12.20 EXPERIMENT 20 - Delayed extinguishing LED

12.25 EXPERIMENT 25 - Connection indicator

Wiring Sequence

2-13, 14-16-20-26, 25-24, 15-18-19-12, 23-11-30, 29-10-17-1

25 26 10KΩ 24 23 100Ω 20 19 16 15 14 13 12 11 10 30 100KΩ 29 18 17 2 1

• Complete all wiring connections as indicated in the sequence.
• Switch on the main switch. Red LED will light up but blue LED will not.
• Press the push switch. Blue LED will light up and red LED will extinguish.
• Release the push switch. Red LED will light up again and blue LED will extinguish.
• This principle can be used for indicating the break/connect of circuit: When the door, car-door or window is closed, it is just like the push switch is being pressed, and thus blue LED lights up while red LED does not. When the door, car-door or window is opened, this is just like the push switch is released, and thus red LED lights up while blue LED goes off.

• Complete all wiring connections as indicated in the sequence.
• Switch on the main switch. After a while the blower will blow.
• Press the push switch, and the blowing speed will be changed for a while. Do not release the push switch, and the speed will gradually back to the original blowing speed.
• And then release the push switch. The blower will stop for a while. After waiting for some time, the blower will resume operation again like it did at the beginning of the experiment!
