7-Segment Counter using NE555 and CD4026

Contents hide

In this DIY tutorial, we are demonstrating the project of a 7-segment counter using a NE555 timer and CD4026 IC. Digital counters are required in this modern world, and seven-segment displays are the best part to show the numbers.

Counters are required in the object or product counters, advanced stopwatches, calculators, clocks, and so forth. To utilize the 7-segment display effortlessly, there is a 7-segment driver IC which is IC CD4026, so we are building a 7-segment counter circuit utilizing CD4026 IC.

7-Segment Display Counter Circuit

Working Explanation

The circuit is very simple. We have interfaced with the display to the IC, which is named IC 4026. PINs 4,5,14 are left open as we haven’t utilized them. To Reset the counter, we have used PIN 15 with the assistance of a push button.

To maintain a strategic distance from the freezing, Pin 2 is kept low, and Pin 13 is kept high to power the IC.

Presently, another fundamental part of this circuit, other than IC 4026, is 555 timer IC. The 555 timer IC is utilized here to give the pulse on each Button. At whatever point we press the button, the counter advance by one.

We have likewise utilized an RC circuit, which is of 22uF capacitor and 100K resistor at timer PIN 1 of 4026, with the goal that it just checks one pulse beat each time button is pressed.
