The code continuously reads the temperature from the LM35 sensor and adjusts the LED's behavior accordingly. If the temperature is below 30.0 degrees Celsius, the LED blinks with a 250 milliseconds on ...

The code for this project is written in the Arduino programming language (based on C/C++). It uses the digitalWrite() function to control the state of the LEDs connected to the Arduino pins. The ...

Motion detection is a common application for intruder alarms, light switches, and other home and industrial automation applications. And there are several ways to do it. We have already used a PIR ...

An infrared sensor is an electronic module that is used to detect the certain physical appearance of its surroundings by either emitting and/or detecting infrared radiation. IR sensors can also sense ...

The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...

Street crime is very common in the modern century. Everybody needs to feel secure when they are at home either while sleeping at night or during day time. So, many security alarm systems are available ...

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor with the help of keypad. Hi there! I hope you are doing great. Today I am sharing the Proteus ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...
