Two-dimensional lantern controller circuit shown in Figure 1 is mainly composed of the NOT gate lCl (CD4069), counting, timing distribution circuit IC2 (CD4017), analog electronic switch IC3 (CD4066) and D trigger IC4 (CD40174). CD4069 logic function and pin is shown in Figure 2a, of which NOT gates F1, F2 and external resistors R2, R3, capacitor C4 form multivibrator to produce a square wave pulse in about 3Hz. R3, C4 are the oscillator timing components. Regulation the two components can change the oscillation frequency.
