This circuit can light up two lights in a cycle. This circuit is an astable multivibrator composed of a transistor (NPN9014, DC magnification should be >200), a red light-emitting diode and R, C components, powered by a 6V DC power supply. The execution of the microcontroller programming process is shown in the figure, and you can see that the two tubes flash alternately.
