This is a circuit diagram showing the random nature of LED 7 segment. In the diagram circuit IC1 – LM555, R1, R2 and C2 on the circuit a sensitive multi-Stable Brett Foster (Astable. multivibrator circuit) function generator signal square (Square Wave) and send the pin 3 of IC1. It can change the frequency by VR1. [...]

This be Random Number Generator Circuit there is the character is 10 LED Flasher by use IC 4017 and IC 4011. For the 4017 IC is a 16-pin CMOS decade counter. It takes clock pulses from the clock input, and makes one of the ten outputs come on in sequence each time a clock pulse [...]

This isn’t a very useful or interesting circuit but it demonstrates the prinicple of a Binary to Decimal decoder IC such as the IC 4511.
