Circuit Description: The push button is connected to digital pin 2 of the Arduino. The other leg of the button is connected to ground (GND). No external resistor is required because we use the Arduino ...

Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

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 ...

In this project, I developed an innovative hardware solution utilizing an Arduino Uno board paired with an ultrasonic sensor to create a real-time object detection system. The primary objective was to ...

Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using ...
