Visitor counter using 4026 counter ic Schematic Circuit Diagram

Schematic Circuit Diagram: Before explaining the project I am going to tell you one important thing; that is please make a habit of the reading datasheet of particular ic you are using in your project. In this project an importantly integrated ic used is   cd4060b you can download from this link. And another important component is a[…]

Power-On Sequencer Schematic Circuit Diagram

This circuit was developed to turn on power supplies in sequence, and then turn them off again in the reverse sequence. This can be helpful for experimenting with equipment and circuits whose power has to be applied and removed in a particular order (like the PC/EPROM-Programmer combination used by Elektor’s Software Service Department; Ed.) The[…]

4-digit counter module

This compact four-digit digital counter is suitable for any application, such as clocks, frequency meters, digital voltmeter, tachometers, stop-watches, scoreboards, etc. The counter module provides a reset switch and a carry output signal. The maximum count of the module depends on which version of the IC used: • the MM74C926 pulls its carry output high when[…]

Digital pattern generator

Digital pattern generator: During the construction and testing of digital circuits, there is often a need for an accurately defined bit pattern. The generator described here uses an EPROM to store the bit information for the desired pattern. When switch S1 is pressed, a given pattern is generated once; seven different patterns can be generated simultaneously. The eighth[…]
