How to Make a Digital Voltmeter, Ammeter Module Circuits
In this article I have explained how to build a digital voltmeter and a digital ammeter combined circuit module for measuring DC volts and current through different ranges, digitally. Introduction Electrical parameters like voltage and current are inherently associated with electronics and with electronic engineers. Any electronic circuit would be just incomplete without appropriate supply […]
Satellite Signal Strength Meter Circuit
Here I have explained how to make a simple inexpensive satellite signal strength meter which can be used for aligning dish antennas with local satellites in order to achieve the correct positioning and maximum signal strength from the antenna. How LNB Works The LNBs that are used for receiving satellite signals (digital or analogue) are […]
Transformerless AC Voltmeter Circuit Using Arduino
In this article I have explained how to make a transformerless AC voltmeter using Arduino. Making an analog voltmeter is not an easy task as to build one you must have good knowledge of physical quantities like torque, speed; which can be very difficult when it comes to their practical applications. By Ankit Negi But […]
0 to 99 Digital Pulse Counter Circuit Diagrams
The proposed 00-99 digital pulse counter circuit becomes very handy in places where you need to keep the people organized in some specified order. Operating details of the digital counter As may be referred the circuit employs the popular 555 IC to genearte the pulse clocks. The pulse counting is done with the help of […]
Accurate Speedometer Circuit
Here we’ll see how a simple yet accurate analogue speedometer circuit can be constructed at home using just a single IC and a few external passive components. The speedometer can be universally used with all 2-wheeler, 3-wheeler, even in bicycles for indicating their speeds. Using Frequency to Voltage Converter In my previous article I have […]
