  Interfacing of LDR sensor with arduino using Tinkercad In this project, we are using LDR as a   Light Sensor with an Arduino to control a LED light and Buzzer as per light condition of the room. The LED light and Buzzer will turns ON automatically when there is less light intensity outside or inside the room   and turns off when it is   bright outside or inside the room. For this, we need LDR sensor to detect the light intensity inside or outside the room. And an Arduino to control the Buzzer and LED It’s like a dark detecting circuit . Circuit Diagram: Components Required: §   Arduino UNO §   LDR (Light Dependent Resistor) §   Resistor (10k) §   LED - 1 §   Buzzer    Connecting wires Connection: The hardware a part of this project is extremely easy to place together. First of all, make the connections for the LDR sensor with the Arduino. The connections for the LDR sensor with the Arduino given in above circuit diagram: Connect one pin of the LDR sensor to the 5V pin on the Ardu

  Interfacing of ultrasonic sensor with an Arduino using Tinkercad In this Project, we will make an alert alarm using the HC-SR04 ultrasonic sensor. The ultrasonic sensor used in this is utilized as a distance sensor, it will give us the distance at which the obstacle is. Using this distance value, we can turn on or off the buzzer and also, we can flash the LED light. Circuit Diagram: The hardware a part of this project is extremely easy to place together. First of all, make the connections for the ultrasonic sensor with the Arduino. The connections for the ultrasonic sensor with the Arduino given below: connection: Connect VCC on the ultrasonic sensor to the 5V pin on the Arduino. Connect the Trig pin on the ultrasonic sensor to pin 4 on the Arduino. Connect the Echo pin on the ultrasonic sensor to pin 5on the Arduino. Connect the GND on the ultrasonic sensor to GND on the Arduino.   After making the connection with ultrasonic sensor, make the connections for the buzzer, LED l

 PIR Sensor Based Security System using an Arduino in Tinkercad  In this project we are going to create a simple security system circuit with an Arduino and PIR motion sensor which can detect movement around it. An LED will light up when movement is detected and also buzzer will turn on. We can use this project as security system in various places in home, ware houses PIR (“passive infrared”) sensors use to sense the motion. We can use PIR to detect whether a human has moved in or out of the sensor’s range. They are mainly found in appliances and gadgets used at home or for industries. Introducing the PIR Motion Sensor: The PIR motion sensor is used to detect movement in particular area. PIR stand for “Passive Infrared”. Basically, the PIR motion sensor measures infrared light which is coming from the objects within its field of range. So, it can detect motion based on changes in infrared light in the environment which is coming from the human being.
