When the battery is loaded, the vibration switch S1 is off, so the circuit does not work. When the spinning gyro

At that time, due to the centrifugal effect, the vibration switch S1 is turned on, the circuit works, and the multivibrator circuit works.

The principle is that when the power is turned on, two triodes Q1 and Q2 will be turned on first, but because of the transistor

A difference, only one pipe is the first to conduct. Then, the two triodes in the circuit conduct in turn.

On and off, the two light-emitting diodes emit light circularly. When the gyro is rotated, the bright LED

There will be a straight line, because the lights are staggered and every two lights turn on alternately, so

A number of dotted patterns appear.

Breathing light, LED is completed from bright to bright under the control of the circuit.

The darkness gradually changes, and then it lights up from the back channel, feeling like breathing.

Power supply voltage: 4-6v DC

Type: TJ-56-162

This kit consists of Q1, Q2 and other multivibrators to control the alternating flashing of two groups of LED lights and 83 LED rows.

The shape of the wind chime and the principle of the multivibrator are as follows. Because the parameters of the components can't be completely consistent, so in

At the beginning of power-on, one of Q1 and Q2 will always be turned on first, assuming that the Q1 line is turned on, and the collector voltage of Q1 drops to 0V. This

Group a LED emits light; Because the voltage across the capacitor can't suddenly change, the 0V voltage at the collector of Q1 makes Q2 through C 1

The base pole position is also reduced to 0v, and Q2 is cut off. At this time, the group B LED does not emit light. With the increase of C1 charging voltage, when it rises to

When Q2 turns on the voltage, Q2 turns on, and the collector voltage of Q2 drops to 0V. At this time, Group B LED lights emit light; Q2 current collection

The voltage of 0V at the pole drops the base potential of Q1 to 0 V through C2, and Q1 turns off. At this time, the group A LED does not emit light. after that

C2 starts to repeat the above process when charging, so that the two groups of LEDs continuously circulate and alternately emit light.

supply voltage

4.5~5V DC power supply (5.5* 2.1mmDC power supply base)

Or three 5th batteries.

• Voltage :3-4 .5 V

• PCB material: FR-4 fiberglass board

• Dimensions: 34 * 34MM

• Circuit functions:

• After the success of the package produced five LED will be with the rhythm of music or other sounds flashing up and can be placed near the sound, allowing light to music dancers!

• Circuit:

• SKD5 melody voice LED lamp is mainly from the power circuit, a microphone amplifier circuit, LED light circuit. Power from the J1 input, C1 filtering supply road use. MK1 the sound signals into electrical signals, coupled to the Q2 C2 the amplified signal to the base of Q1, Q1 driver 5 by the LED light, the greater the sound, LED lights brighter.

This suite uses three two-digit digital tubes to display the hours, minutes,

Seconds, use two small L ED instead of colon for interval. Using a single chip microcomputer

Programmable control display, using timer to time, high accuracy, can be

The time can be adjusted by a button, and it also has a memory battery and a main power supply.

Disconnected time is still running (the digital tube does not display). It is practical.
