It uses two different types of transistors and uses the principle of capacitor charging and discharging to make the two
transistors turn on and off in turn, and the light-emitting diode flashes automatically.
The flash frequency is determined by the capacity of capacitor C2 and resistor R. It also has an impact on flash frequency.
