An Automatic LED Emergency Light circuit is designed to turn ON when there is no adequate lighting or if the power supply is cut-off. Earlier fluorescent lights were used to build such circuits. But the use of LED's have proven to provide adequate lighting for a longer period before draining the ...
A motion sensor light circuit is a circuit in which a light turns on when motion is detected. With a PIR motion sensor integrated with an arduino, we can detect movement and program the arduino to turn a light on for a certain period of time once this motion is detected.
This is basic arduino tutorial; turn on LED when it's dark and turn off when is light. Required Hardware : Arduino Board LED LDR (Photoresistor) 220 and 10K Resistors Jumper Wires Breadboard ...
Automatic LED Street Light Using Electronics LDR Sensor - Electricity DIY Project - Hello Friends, here I will show you how to make LED street lighting using LDR electronics sensor. This is the ...
In this simple project, we are going switch ON a LED automatically during night time or when we moved into a dark room. To complete this project we need light dependent resistor (LDR), 10K potentiometer, LED, 150 ohms resistor, BC547 transistor or any general purpose transistor.
So to flow current we have to apply have current on base for flow current, so we off the light. Resistance of LDR is low current will flow it and apply on base. When current is passes from base current will also flow have transistor then passes form led. LED is on, again when you on the light led off. Dome Video of automatic street light:
This is a motion sensor light circuit that turns on when there is any motion, whether in the light or in the dark. Many times, it is only wanted for motion sensor lights to come on when it is dark. If it already bright, then many times we wouldn't need the light to turn on.
Light Sensor Circuit Working Operation. The light sensor circuit is an electronic circuit designed using (light sensor) LDR, Darlington pair, relay, diode, and resistors which are connected as shown in the light sensor circuit diagram. A 230v AC supply is provided to the load (in this case, the load is represented with a lamp).
Automatic dark detector senses darkness. As the light level decreases and LDR meets the maximum threshold resistance, the circuit automatically switches on the LED D1. Dark sensor with variable resistor: A dark detector can be made using a variable resistor. The sensitivity of the circuit can be adjusted with a variable resistor.
Summary of LDR circuit for automatic light system: This circuit is based on Light Dependent Resistor (LDR) which 'll turn on LED's when ever darkness is sensed in room. You can put this small lamp in your kid's room as a simple emergency lamp to avoid panic situation in case of sudden power failure.

We previously made many Circuits using LDR, which use LDR to automate the lights according to requirement. Working of LDR controlled LED using Arduino. As per the circuit diagram, we have made a voltage divider circuit using LDR and 100k resistor. The voltage divider output is feed to the analog pin of the Arduino.
This automatic staircase light circuit switch on the staircase lights automatically when someone enters on the stairs and gets off after some time. There are two important components in this circuit, first is PIR Sensor (Passive Infrared Sensor) and second is Relay.

A very simple automatic solar light system for illuminating your garden passages can be built using some LEDs, a rechargeable battery and a small solar panel. The system automatically switches ON the lamps at dusk and switches them OFF at dawn.
These energy saving street lights make use of incandescent lamps instead of LEDs.So here I will teach you how to make an electronic circuit for street light automation. The heart of this circuit is a LDR (Light Depended Resistor) which is connected as a potential divider with a 56K resistor.
Simple Circuit for Every Electronics Beginners : #Automatic Night Lamp With LDR: Hey, guys ☺ Looking for some beginning DIY projects in electronics..! then you have come to the right placeIn this project, I'm sharing my first electronic project.Which I teach to every new one in electronics.....
This is the simple and cost effective automatic LED Emergency Light Circuit with light sensing. This system charges from main supply and gets activated when main supply is turned OFF. This emergency lamp will work for more than 8 hours (depending the battery capacity and the power consumed by the LEDs).
presents an automatic street light controller using light dependent resistor(LDR). By using this system manual works are removed. The street lights are automatically switched ON when the sunlight goes below the visible region of our eyes. It automatically switches OFF the street lights under illumination by sunlight.
A cheap and simple automatic night light using few transistors and NE555 timer is shown here. The circuit will automatically switch on the AC lamp when night falls and the lamp will be automatically switched off after a preset time. The working of this night light circuit very simple. An LDR is used as the sensor here.
