Automatic Fence Lighting with Alarm

Engineeering Projects
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…

laser based communication link transmitter circuit

Communication is an essential part of our daily life. The project; “Laser-Based Communication Link” allows people at a distance of around 500 meters to communicate wirelessly through a laser. Various other laser-based projects posted on bestengineeringprojects.com are:- (a) Speech Communication using Laser (b) Mini Laser Turret (c) Laser Voice Transmitter Circuit The project unlike other wireless media uses laser light from the transmitter torch as a carrier instead of RF signals used in the conventional system. At the receiver end, the phototransistor should be aligned in a line of sight position…

verified electronics projects

Verified Electronics Projects: Those practicing the art of engineering are concerned with numbers in all phases of their work. One area where the numbers become overwhelming is in the area of electronic projects and their parts. Although the integrated circuit (IC) has been a boon to the electronics engineers/hobbyists, the sheer number of parts almost requires the user of the electronic project to have research assistance as an associate, to be sure all electronic projects are available have been considered for use. Valuable time is often spent poring over the…

motor controller circuit for washing machine using 555

Washing machines have been an important part of our daily life. But, the issues we have to deal with in a few months of using them make it more difficult. Previously, we had already posted the Automatic Washing Machine control circuit. It is because most of the washing machines have a single-phase motor incorporated in the system and the timing and direction of the motor are controlled by an external mechanical switch which gets worn out so easily and is not economical on the other hand. And, the project “Motor…

interfacing of 4 lcd using arduino

Liquid Crystal Displays (LCD) are activated by an AC signal across s selected display segment; this feature is included in the LCD module itself. In addition to the standard data input, there is also a display frequency input terminal. The circuit “Multiplexed 4 LCD Display using Arduino UNO” can drive most LCD display. This circuit is used in auto dash board displays, panel meter, wall and table clocks, calculator. In this article we are going to show, how to make 16×8 display using four 16×2 display by using common data…

sound meter circuit using arduino

The circuit posted here is of sound level meter using arduino uno board, microphone, Amplifier section and LCD module. The basic function of this project is to measure the intensity of sound and display the result in LCD module. This project can be used in any small closed room like living room, class room etc. The result of sound level is display in LCD module in decibel unit. Here, we had used normal microphone despite of any expensive microphone or sensor. We had already built a sound level meter using…

car reverse alarm using arduino

Arduino Based Car Reverse Alarm: We prefer to stay alert than to face the consequences as the result of our ignorance. They say, ‘Prevention is better than cure’ and this project; “Car Reversing alarm” serves us the right purpose. It is designed such that the device sounds an alarm as individual reverses a car for parking in a specific location and it detects any sort of obstacles there, that may create unwanted troubles. The device outputs audible sound wave as well as a visual indication to make the individual aware…

automatic wiper system for automobile using arduino

Automatic wiper for Automobile using Arduino and Rainsensor: The project we are talking about is an automatic screen wiper system that monitors the intensity of rainfall and controls the frequency of operation of the wiper accordingly. According to WHO, more than 1.25 million people die every year because of road crashes and mostly in rainy seasons. People end up dying because of small mistakes. Here we have forwarded an attempt to reduce that number. The project is especially suited for car. The project is centered around Arduino UNO board. So…

Metal Detector Circuit using Arduino

Engineeering Projects
metal detector using arduino

A metal detector circuit using Arduino is an electronics device that is used to detect metallic abject like metal coins, iron ore, aluminum or silver, gold, etc. This device can be used in a place where metal detection is mandatory like a hospital, airports, etc. because it can be harmful. We had already posted a simple metal detector circuit using transistors and RC components. The working principle is the same excepting the processing circuit. The metal detector circuit posted here uses an Arduino UNO board or equivalent. This project can…

automatic float charging circuit

Automatic battery float charger circuit: This article aims to develop a battery charger circuit using the principle float charging technique. Afloat charger is also referred to as a smart charger, maintenance charger, or storage charger because it charges the battery at the same rate at which it self-discharges. The main reason for using a float charger is, that it protects the battery from overcharging and deep discharging. Thus, you can connect the float charger circuit to a battery for indefinite intervals of time i.e. there is no need to disconnect…
