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 […]

Digital Thermometer Circuit – Uses a Solar Cell for Power
The articles explains a digital thermometer circuit project that works without a battery. Instead of a battery the circuit utilizes a small solar cell and operates by deriving power from the ambient light available from the surrounding light sources. This allows the circuit to be extremely compact, light weight, versatile and hassle free while measuring […]
Digital Clock Synchronized Programmable Timer Circuit
I have already discussed one programmable timer circuit in this blog earlier, the circuit involves the IC 4060 for generating the basic oscillations which is further used for generating the required time intervals, however this cannot be synchronized with an external clock. The following circuit was requested by Mr.Amit, here the concept makes use of a clock for acquiring the required base timing […]
Simple Arduino Digital Ohmmeter Circuit
In this post I will show how to construct a simple digital ohmmeter circuit using Arduino and 16×2 LCD display. We will also be exploring the other possible circuit ideas using the same concept. Circuit Objective The motto of this article is not just making an ohm meter to measure the resistance; your multimeter can […]
Digital Buffer – Working, Definition, Truth Table, Double Inversion, Fan-out
A buffer stage basically a reinforced intermediate stage which allows the input current to reach the output without getting affected by the output loading. In this post I will try to explain what digital buffers are, and we will be taking a look at its definition, symbol, truth table, double inversion using logic “NOT” gate, […]
Digital Voltmeter Circuit Using IC L7107
In this post I have explained a very simple digital panel type voltmeter circuit using a single IC L7107 and a few other ordinary components. The circuit is able to measure voltages right up to 2000 AC/DC V. About the IC L7107 Making this simple digital panel voltmeter circuit is particularly easy due to the availability […]
