When the terminal outputs high level, the corresponding KN makes the illumination circuit connected. When the terminal outputs low level, KN makes the illumination circuit disconnected. For example, when Q1 terminal outputs high level, V1 is connected which will make KN1 connected. The first circuit of illuminations will be illuminated. When Q1 terminal becomes low level. V1 is disconnected and KN1 is disconnected. HL1 are off.Q1-Q8 keep changing the states under the control of the clock pulse. Then HL1-HL8 will be controlled to show various illumination effects. S1 and S2 are used to set the initial state of the bidirectional shift register. Then push S4, write the set parameter to the shift register. If S1 is connected and P1 terminal outputs high level, IC's Q1 terminal will output high level. S3 changes the shift register's shift directions by controlling the low-frequency multivibrator. Put 53 to ALTERNATION , the low-frequency multivibrator will begin to work.
