The History Of Timer Ic. Ticking Sound Using Ic
We have designed a system where there is automatic turning on and off of the light whenever required. When darkness is detected then the sensor circuit gets activated and switches ON automatically and when there is other source of light during daytime, the street light gets OFF. Also this circuit can be used to adjust the sensitiveness of the light. The circuit is cheap and economic and can be made easily.

The Timer Power-ON delay circuit can be used in various projects where for a certain amount of time you need to turn on a specific load. The aim of this project is to turn on the load any time you press the button or activate a sensor for a few seconds. This timer-based delay circuit can also be used for turning the buzzer ON in the security systems for a certain period of time that can be calculated using the formula discussed above.
The term LDR is known by many names such as a light-dependent resistor , photoresistor, photoconductor, the photocell. The term photocell is most widely used in datasheets as well as instruction sheets for domestic gear. The light-dependent resistor is a low-cost photosensitive element and was used in photographic light meters as well as in various applications like flame detectors, card readers smoke detectors, burglar detectors, and lighting control in street lamps. This article discusses bout LDR projects for engineering students. Project work for students helps to enhance technical skills in engineering.
Automatic Street Light control system using Timer IC- The Automatic street light control system is seriously an amazing project and no doubt this is one of my favorite projects. This is a very small project build around a few electronic components. In this project, you will learn how to make an automatic street light control system using timer IC and an LDR. You can also use this circuit in lawns and in laser-based security systems. Before, I am going to explain the circuit; first, I would like to explain why we need this circuit in the first place and how this project works. In my previous tutorial, I explained everything about the timer IC including the pinout, basic working principle of the timer IC , different modes of operation, Monostable, Astable, and Bistable.
Did you ever think that how the street lights automatically turn ON in the night and turn OFF automatically at morning? Many people have a phobia of darkness, so to assist them in such situations, we have explained a simple circuit that will automatically turn on the street light consisting of LEDs or bulb coupled with relay. It is lit well enough to see the objects nearby. This circuit is very easy to work around and also it is battery operated. The power consumed by the circuit is very low because of the very few components used in the circuit. The whole circuit is based on IC LM, which is basically an operational amplifier that is configured in a voltage comparator.
We have designed a system where there is automatic turning on and off of the light whenever required. When darkness is detected then the sensor circuit gets activated and switches ON automatically and when there is other source of light during daytime, the street light gets OFF. Also this circuit can be used to adjust the sensitiveness of the light.
T he circuit diagram present here is that of a street light that automatically switches ON when the night falls and turns OFF when the sun rises. In fact you can this circuit for implementing any type of automatic night light. When there is light the resistance of LDR will be low. So the voltage drop across POT R2 will be high.
