The complete circuit diagram for this project is given below, as you can see it uses an Arduino nano. But we can also build an obstacle avoiding robot using Arduino UNO with the same circuit (follow ...

This Arduino project utilizes a Passive Infrared (PIR) sensor to detect the presence of obstacles and an ultrasonic sensor to measure the distance to the detected obstacle. The system is designed to ...

Setup Connect the components as per the circuit diagram. Upload the provided code to the Arduino using the Arduino IDE. Power the system and observe the buzzer alert when an obstacle is detected ...

An obstacle avoiding robot is one of them. It uses a technique to change the path if it detects any obstacle in its way. (Picture Courtesy: Circuit digest) In this project, an Arduino based obstacle ...

Build a simple LPG gas leakage detector using Arduino and MQ-5 sensor. This beginner-friendly project features buzzer and LED alerts, circuit diagram, and complete Arduino code for home safety.

One of the essential parts of any home security system is a door detector that lets you know when a door opens. Over on Adafruit, they show you how to build your own that hooks into IFTTT so you ...
