The Traffic light controller circuit. use the LEDs for display and the digital circuit as based, include IC-4027,CD4017,IC-555 and so easy and cheap. [...]
When we want to use flip-flops with CMOS. Often we meet CD4027. It is dual J-K flip-flops that are monolithic complementary MOS integrated circuits. We have seen many circuits that…
This is 2 Digit Simple digital counter circuit using CD4026 as main parts can display with LED 7 segment 0-99 number There is a reset button to restart.
A CD4069 consists of six inverter gate circuit in 14 DIP packets. It is made with CMOS technology so can be use on wide supply voltage range : 3.0volts to 15volts,low power consumption
