Last and finally, we have the photodiode and the IR emitting LED pair which all together make the total IR Proximity Sensor Module. Types of IR Sensors for Arduino Projects There are several types of ...

Music-reactive multi-color LED lights project. In this project, a simple 5050 RGB LED strip (not the Addressable LED WS2812), Arduino sound detection sensor and 12V adapter were used. So how does it ...

This project demonstrates a simple water detection system using an Arduino board and a water sensor. The system uses an LED to indicate whether water is detected. The LED turns ON when no water is ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor ... an LED to alert the user when it is time to water a potted plant, and/or turn on a water ...

In this article, I have added three sensors with Arduino ... sensor that checks for the environment and detects the presence of flame, just like a smoke detector detects smoke. Once it does its work, ...
