In this post we are going learn how to construct 3 different frequency counter circuits using ordinary components and ICs which will showcase the measured frequency on 7 segment displays. The first circuit which uses 4026 ICs can measure frequencies up to 1 MHz and the circuit is user calibrated. We will Learn About: Block […]

5 Digit Frequency Counter Circuit
This digital frequency counter will provide a direct reading of the frequency applied at its input, through a 5 digit common cathode display module. The compact frequency counter can be used for accurately counting the frequency or pulse from any intended source. Main Applications It can be also used for measuring the RPM of a […]
How to Make a Transformer Winding Counter Circuit
In this post I have explained how to make a simple transformer winding counter circuit using ordinary LEDs and also through an advanced digital display circuit. The idea was requested by one of the dedicated readers of this blog Circuit Objectives and Requirements I want a circuit which counts a number of turns for winding […]
