Automatic Street Light Controller Circuit Using LDR And 555 Timer IC

Automatic Street Light Controller Circuit Using LDR And 555 Timer IC   We are living in the world where everything goes to be automatic from your washing machine to your ceiling fan. Street lights are one of those   examples   of the automatic world. Automatic street light are those light which needs no manual operation to gets turn ON and turn OFF. Did you ever try to make such kind of street lights that gets turn ON and turns OFF automatically? In this article, we are going to make automatic street light using LDR and 555 timer IC. List of Components   555 Timer IC LDR LED Potentiometer Resistor 1* 1k ohm  Resistor 1* 220 ohm 9V Battery Printed Circuit Board(PCB) Or BreadBoard  Circuit   Diagram A very simple circuit diagram of automatic street light is given below.  Automatic Street Light Controller Circuit Principle and Working of Automatic Street Light Controller 555 Timer IC is the main part of the circuit tha...

Ultrasonic Distance Sensor in Arduino With Tinkercad

  Ultrasonic Distance Sensor in Arduino With Tinkercad Let's measure distances with an ultrasonic rangefinder (distance sensor) and Arduino's digital input. We'll connect up a circuit using a breadboard and use some simple Arduino code to control a single LED. You may have already learned to   read a pushbutton   and   PIR motion sensor   with Arduino's digital input, and we'll build on those skills in this lesson. Ultrasonic rangefinders use sound waves to bounce off objects in front of them, much like bats using echolocation to sense their environment. The proximity sensor sends out a signal and measures how long it takes to return. The Arduino program receives this information and calculates the distance between the sensor and object. Find this circuit on Tinkercad Explore the sample circuit embedded here by starting the simulation and clicking on the proximity sensor. This will activate a highlighted area in front of the sensor with a circle ...
