At present, all kinds of lotteries are booming in the whole country, among them, it is more difficult to choose “6 + 1” sports lottery numbers. Some Lottery phone number, date of birth, etc. as an alternative, but also useful craps, pumping poker election number. This article describes a homemade “” 6 + 1 “type body color selectors”, the circuit principle as shown in the figure. This circuit provides an entertaining selection method for electronics enthusiasts. I. Introduction of IC Function and Function 1. CD4060 (IC1) is a 14-bit binary serial counter / divider / oscillator that functions as an oscillator and frequency divider and provides counting pulses for IC2A.
