The ultrasonic sensor catches the object as it comes in its range (range decided in the code). So before the starting of the project , the code is to be written (on IDE) and uploaded in the Arduino ...

In this tutorial we are going to interface RCWL-0516 Doppler Radar Sensor with Arduino Nano. The RCWL-0516 is a motion detection sensor. It can detect motion through doppler microwave technology ...

What if we can generate different colors using a single RGB led and make our room’s corner more attractive? So, here is a simple Arduino based color mixing lamp which can change color when there is ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor with the help of keypad.

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 ...
