555 simple seven color lamp circulation control circuit
This seven color lamp circulation control circuit is composed of the DC step-down rectifier circuit, the time base pulse generator, the synchronous addition counter and the SCR trigger color light circuit, the circuit is as shown in figure 17-57. The IC3 uses the 1/2 double binary adding & counting integrated circuit CD4518 as the multi-level synchronous counter. If you jump the time counting on the clock signal and connect the counting output terminal Q4 with the reset terminal R, so you constitute the circulation technology circuit. VT1, VT2, VT3 respectively connect to the output port Q1,Q2,Q3. The alterable colour unit is composed of the red, green, blue gezer lamp.
