In this post I have explained how to build a simple yet accurate digital sine wave generator circuit, which is basically an oscillator circuit, enhanced to generate square waves through incrementing steps, which ultimately appears like a stepped sine waveform. By Ron Mackenzy The difference between analogue sine wave generator and digital sine wave generator […]

2 Digital Potentiometer Circuits Explained
In this post I have explained a 2 simple, single chip digital potentiometer circuits which can be controlled through a single pushbutton, a dual pushbutton (up/down) or even through external digital (CMOS/TTL) input triggers. 1) About DS1869 Dallastat TM is a rheostat or potentiometer. This unit delivers 64 conceivable consistent tap outputs over the over-all […]
Arduino Digital Clock Using RTC Module
In this post I will show how to construct a digital clock using RTC or Real Time Clock module. We will understand what “RTC” module is, how to interface with Arduino and what it does. RTC module is a circuit, which keeps track of current time accurately. It does two functions, it communicates with microcontrollers […]
Converting Analogue to Digital (Analogue Read Serial) – Arduino Basics
In this Arduino basics I have explained the code implementation procedure wherein an external analogue signal is fed to the Arduino analogue input and translated or converted into a correspondingly proportionate digital readout. Here we employ a variable resistance in the form of a pot as the analogue signal source. Analog Read Serial In this […]
Digital Capacitance Meter Circuit Using Arduino
In this post I will show how to construct a digital capacitance meter circuit using Arduino which can measure capacitance of capacitors ranging from 1 microfarad to 4000 microfarad with reasonable accuracy. Introduction We measure value of the capacitors when the values written on the capacitor’s body is not legible, or to find the value […]
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 […]
