Function Description.

The eight-channel answering machine consists of answering key, priority encoder, decoder display circuit, latch circuit, reset circuit and sound circuit. The priority encoder is composed of discrete components; the decoder display circuit shows the number of robbing. According to the situation of the answer, the answerer displays the priority of the answerer's bit number, and at the same time, the buzzer sounds, that is, the answer is successful. It is a comprehensive training kit to improve circuit analysis and skills.

5.Product Model:ZY-12 

Working power supply:DC 3~4.5V

PCB board size: 35mm * 23mm Function Description.

This kit is made after the success of the 5 LED will flash with the music or other sound rhythm, can be placed near the stereo, so that the lights for the music dance!

Product Model:ZY-30

Working power:DC 4.5V

PCB board size: 34mm * 24mm Function Description.

The core component of this circuit is the 555 integrated timer, which works in the unregulated mode of operation, after the power supply is turned on, the output of the 555 integrated timer 3 feet of the level of constantly high and low level changes, when the 3 feet for the high level, LED1 is off, LED2 light, while the capacitor C3 is charged, the speaker sends out a ‘’ sound; when the 3 feet for the low level, LED1 is off, LED2 light, while capacitor C3 is charged, the speaker sends out ‘’ sound. sound; when 3 feet for the low level, LED1 light, LED2 off, while capacitor C3 discharged through the speaker speaker and issued a ‘ta’ sound. So the light-emitting diode alternately light, the speaker issued a ‘beat sound.

Product Model:ZY-34

Power supply:DC 3~5V

PCB board size:44*26mm

Function Description.

Clap your hand, LED light, and then shoot some extinguished, so the cycle, high sensitivity, in about 4 metres can be clapped control

Model:ZY-48

Power supply:DC5V

PCB board size:4.3*3.5CM

Function Description.

This circuit is a polyharmonic oscillator composed of 555 integrated circuits. When you press SW1, the power supply through D2 to C2 charging, when the IC U1 foot 4 (reset terminal) voltage is greater than 1V, the circuit oscillation, the speaker issued a ‘ding’ sound. Release the button SW1, C2 capacitor storage of electrical energy through the R4 resistor discharge, but the integrated circuit 4 feet continue to maintain a high level and keep oscillating, which is due to the R1 resistor access to the oscillator circuit, the oscillation frequency becomes lower, so that the speaker emits a ‘thud’ sound.

Product Model:ZY-52

Power supply:DC 6V

PCB board size:75*35mm

Function Description.

When power on, 7 LEDs will display a random number of points, the player presses the switch S1, 7 LEDs will all become bright, about a few seconds later, 7 LEDs began to flash until the last display of a stable number of points. The whole process of ‘rolling dice’ is over.

Product Model:ZY-54

Power supply:DC 3~5V

PCB board size: 26mm * 24mm

Function:After power on the 2 white blue LED flashes alternately, if you lengthen the time between light flashes can increase the capacity of the 2 electrolytic capacitors. This kit is accompanied by a schematic diagram analysis, in each set of supporting paper instructions.

Graphic Details

This is a mini ultrasonic levitation small device to levitate foam balls. The device consists of 1 microcontroller, 1 driver chip and 2 ultrasonic probes. Mainly used for students or DIY electronics enthusiasts to learn about ultrasonic standing wave levitation. Does not support the control of levitating objects up and down.

Working principle: ultrasonic standing wave levitation is through the ultrasonic transmitter and reflector (or another transmitter) there is a certain distance (called the resonant cavity distance), the transmitter and reflector (or another sound wave) constantly with the addition of the final formation of standing wave, the standing wave node in the object by the acoustic force to overcome the effect of gravity and ultimately achieve the effect of levitation.

Name:Ultrasonic levitation kit
