Circuit Project Electronic

When you want the counter circuit since 0 arrive at 99. I thinks this circuit may on the same wave length you certainly. it uses IC LM4017 decade counter/divider follow circuit picture. When feed a signal clock at 14 pin cause the position logic at a pin output. From 0 to 99 for switch S1 perform choose RUN or Reset. Please see circuit picture will understand increasingly. Almost forget integrated number this circuit, want the fire feeds 3V low arrive at 15V because be IC digital CMOS there.
