Kit parameters:
Power supply voltage: 4.5-5.5V (DC voltage, 3 battery boxes are recommended)
Board size: 2.5*3.5cm
Buzzer: 5V passive buzzer, the sound of tap-tap-tap is small, please carefully if you mind!!
Function Introduction:
After power on, NE555 outputs a certain frequency of square wave pulse. The high level lights one lamp and the low level lights the other lamp, so the two LEDS flash alternately and there is a clicking sound.
This kit needs to be welded and installed by the buyer himself.
Circuit introduction:
The core component of this circuit is the 555 integrated timer, which works in the non-steady mode. After the power is switched on, the 3pin level at the output end of the 555 integrated timer constantly changes its high and low level. When the 3pin is at high level, LED1 goes out and LED2 shines.
When the 3 feet are low, LED1 shines and LED2 goes out. At the same time, capacitor C3 discharges through the loudspeaker, and the loudspeaker makes a "tap" sound.
So the leds light up alternately, and the speakers make a tap-tap-tapping sound.
