✨ Both ends of the module have a structure with metal buttons, which allows for quick connection between modules.

✨ Various circuits such as lights, fans, radios, etc. can be assembled quickly.

➡ Temperature controlled light

✨ If the temperature exceeds 40 degrees Celsius, the bulb will automatically turn off

➡ Magnetically controlled light

✨ When the magnet approaches reed 13, the bulb lights up; when the magnet moves away, the bulb goes out.

➡ Fluorescent flying saucer

• Ancient bamboo dragonflies and modern helicopters use this principle!

✨ The principle of flying saucer

• When the fan blades rotate, they push the air downwards, generating an upward-facing reaction force that pushes the fan blades into the air, creating a flying saucer.

• The direction of rotation of the motor is crucial for the smooth floating of the fan blades. If the direction is reversed, the airflow directed at the blades will also be directed in the opposite direction, pushing the air upward and forming a fan.

➡ Voice Controlled LED

✨ Blow into the microphone and the LED will flash.

➡ sound and light radio receiver

✨ Blow into the microphone and the LED will flash.

✨ How the radio station works

① Carrier generator: generates high-frequency current

② Microphone: Replaces sound signals with electrical signals

③ Modulator: Load the audio signal to high frequency current.

④ Antenna: Sends electromagnetic waves

✨ How radio works

⑤ Antenna: Receives various electromagnetic waves

⑥ Select a signal demodulator with a specific frequency:

⑦Speaker: Converts audio signals to audio

➡ Automatic light controlled street lamp

• As soon as it gets dark, the streetlights turn on automatically.

✨ Explanation of the principle

• Automatic street lighting: Under the influence of a photoresistor, when light falls on it during the day, the transistor is not turned on and the bulb is not lit.

• At night, when there is no light, the transistor is turned on and the bulb lights up.

• The base current is regulated by an adjustable resistor that adjusts the brightness of the bulb.

➡ lie detector

• Use the lie detector simulation and see if you are lying!

✨ Explanation of the principle

• Automatic navigation lighting: This is a positive feedback system using a capacitor in combination with photoresistor characteristics.

• During the day, with strong sunlight, the resistance of the photoresistor is very small, which causes the loss of conduction current through the transistor base and cut-off, and as a result, the burnout of the bulb.

• At night, with a shortage of light, the resistance of the photoresistor increases, which causes the conduction current to flow through the transistor and its oscillation, and as a result, the flashing of the bulb.

➡ Morse alphabet transmitter

✨Explanation of the principle

• Use the "ticking-ticking" sound to convey information! Create your own passwords with friends.

➡ temperature overrun alarm

✨ When the temperature exceeds 40°C, an alarm will sound.
