The post presents a simple transformerless 1.5V DC power supply circuit which can be used for powering wall clocks directly from mains, and also keep a stand by back-up cell fully charged for enabling an uninterrupted operation of the clock even during mains failures. The idea was requested by Cheekin Warning: This circuit is not […]

Digital Clock Circuit Using 16×2 LCD Display
In this post I have explained how to make a simple digital clock using Arduino and a 16 x 2 LCD display. Introduction As an electronics enthusiast at a stage we would have thought, how to make a digital clock, especially who are interested in the field of digital electronics. In this article we are […]
Make this 7 Segment Digital Clock with Beep Alert Circuit
In this post I will show how to construct a digital clock using 7 segment LED display with Arduino controlled design. How the Circuits Works The proposed 7 segment clock circuit is inexpensive and even beginner in Arduino can accomplish it with ease. This clock consists of four 7 segment displays, two for hours and […]
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. By: RTC module is a circuit, which keeps track of current time accurately. It does two functions, it communicates with […]
Simple Digital Clock using LM8650 IC Circuit
The digital time clock explained here is a circuit which most electronic amateurs would love to make. You might have heard about digital clocks made from clock ICs such as the popular LM8361, MM5387 etc but these ICs could be today quite obsolete and/or complex to build. Circuit Operation The present design is much easier […]
Digital Clock Activated Water Level Controller Circuit
An automatic clock time triggered water level controller circuit which responds to a real time clock input is discussed in the following article. The design also includes a water detection stage which makes sure the initialization takes place only in the presence of water in the tank or the pipe. The idea was requested by […]
