Connect the dual-door 4093 quad 2 input flash Schmitt trigger COMS chip to the non-stationary oscillator circuit. Two 4017 integrated circuits have six LEDs connected to their first six outputs. As the clock pulse enters the pin14 of the two 4017 integrated circuits, it counts from 1 to 6 over and over again. When S1 or S2 is released, one LED of each circuit will continue to indicate a number from 1 to 10. After the circuit is set, by pressing S1 and S2 at the same time, the sensor can be scrolled together, or one sensor can be scrolled at a time.
In 2008,a new industrial park of Liandajin was built in Daya Bay National Economic Development Zone,huizhou with CNY120 million.The Park covers an area of 20000 square meters including 12000 square meters of manufacturing plant,The employees has been up to 1000 and the output has been 60000 square meters per month.
