This is the simpledigital counter circuit, the IC application number 4029 from binary data, and then sent to the IC number 4513, a driver IC 7 Segment, to show off a digital number from 0 to 9.
When entering into a pulse signal input pin 15 of IC1, it will signal to the output signal is Binary.Then send the output from the pin Q0, Q1, Q2, Q3, and the pin. 6, 11, 14 and 2 of IC1.Go to the input of IC2 No. 4513. Which is IC displayed by the decoder signal to the Binary LED display with a 7 or the 7 Segment, will be displayed from a digital number from 0-9.
