battery level indicator circuit

The circuit ‘Battery Level Indicator’ is simple, cheap, and compact. It can be used in emergency lights and other power supply circuits. We are using this simple circuit ‘battery level indicator’ for over a year and has found it works well in emergency light as well as battery charger circuit. We already indicate various battery voltage states using IC, this time we come with a little different concept and circuit for battery indication. Other battery level circuits posted in bestengineeringprojects.com Battery Status indicator Circuit 10 Level Battery Charge Indicator Circuit…

Single Phase Preventer with Under/Over Voltage Cutout

Engineeering Projects
single phase preventer with under over voltage cutout

For a 3-phase induction motor, all three phases of the supply must be present. If any of the phases is missing, or a fuse is blown, the motor will continue to run with two phases only. But in that case, it will draw a very large current, and it may burn unless switched off immediately. To solve this problem the project “Single Phase Preventer with Under/Over Voltage Cutout” is posted here. For the protection of a three-phase induction motor, various types of starters are utilized. But the problem with Starters…

light switching circuit

There are some projects from which every electronics hobbyist starts their journey toward electronics. Same like another hobbyist I had also started my journey of electronics projects by making a very basic project called a light-operated switch using a single transistor. After six long years of the journey today, I had again come up with a basic project which will surely help beginners. The project posted here is of Light Sensor Switch Circuit using LDR and 741 IC. The project switches on the electrical bulb according to the intensity of…

smart dustbin circuit using arduino uno

Dustbin have been important part of our life. But, the issue we have to deal is its open cap. Due to this open cap, insect and flies visit the garbage and also the same flies roam around out kitchen or lunch buffet. This leads to serious health issue. In order to solve this issue, we had design here a Smart Dustbin using Arduino Uno. This smart dustbin automatic open its cap when we pass our hand above it. Component Required for Smart Dustbin usign Arduino Uno Arduino Uno Board Servo…

Earthquake Detector Circuit using Vibration Sensor Here, in this article you will find step by step tutorial on earthquake detector and indicator circuit using vibration sensor which detect the seismic vibration of earth and alert by generation beep sound. Previously, we had already posted two different projects on earthquake detection and indication Earthquake detector using arduino an acceleration Earthquake alarm Earthquake detector using arduino utilize accelerometer in order to detect seismic vibration where earthquake alarm uses geo-mechanical detector. But in the project posted here utilize piezo vibration sensor for MEAS…

Security is a major concern in today’s world. Criminal minded people, who find robbing as a better way of earning, are increasing more day by day. Previously, we had posted Accident Detection and alert system using arduino which also works on same logic. Automobiles are more vulnerable to theft since there are tons of vehicles left unused and the fact that each part of the system provides quite a good amount of money makes it more fascinating. Among many other automobiles, cars top the list of being stolen globally. Thieves…

touch switch circuit using bc547

Today, I have come up with another simple but very applicable project ‘Touch Switch Circuit using Transistor’. With this simple project, you can modify your existing electrical/ electronic appliance with a modern touch facility. A few days earlier I bought a reading lamp from one of the Chinese stores, the design of the Chinese product is quite impressive. The thing that motivates me to write this post is touch facilities i.e. you can on and off the lamp by simply touching the touch plate. The circuit posted here used two…

proteus simulation output 2

How to interface the 4×4 keypad and atmega32 with a single pin? While working with most of the electronic projects, you might have noticed one thing in common; they involve several multiple connections between the components used and the microcontroller. Well, it does seem a necessity too, since doing some hardware work in a certain way is not a piece of cake. Because of this, we are compelled to remove some components or include an additional microcontroller in the project which makes it bulkier and less convenient. To address this…

sound VU meter using ATmega31

A Volume Unit (VU) meter is a standard device that represents the signal level in audio equipment. This project “VU Meter Circuit using ATmega32” makes the representation process much easier since it avoids the use of any physical medium to establish the connection between the audio equipment or audio source and the circuit of the project. This way we can eliminate the hassle of using more components. It uses a bar graph LED for a visual representation of the audio. ATmega32 is an 8-bit AVR (Alf and Vegard’s RISC processor,…

automatic fence lighting circuit with alarm

Today, in this article we are going to teach you how to make an automatic fence lighting circuit with an alarm using op-amp 741 and timer IC 555. Fence lighting is used for security purposes and can be used at various places like door alarms, pathway alarms, etc. where monitoring is required. Various types of fence lighting circuits are already available over the internet but the problem with that circuits is they required high precision alignment. To overcome this problem, we designed a very sensitive automatic fence lighting circuit. We…
