Adjust the potentiometer to see the LED brightness change accordingly. Conclusion This simple project is an introduction to reading analog sensors and controlling outputs based on the sensor's value ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Build a Speed Sensor using Arduino with IR speed sensors to accurately measure the speed of moving objects. This tutorial covers circuit design, sensor calibration, speed calculations, and optimized ...

In this tutorial, we are going to interface E18-D80NK IR Proximity Sensor with Arduino. The E18-D80NK is an advanced low-cost IR Proximity Sensor with an obstacle detection range of 3 cm to 80 cm.

Grove - Infrared Reflective Sensor is used to detect the presence of an object within a specific range. The sensor consists of an IR LED and a photosensor (phototransistor) pair.

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

For patients to receive good care, doctors must be present. To administer medication or provide treatment, he can’t be everywhere at once. If we regularly examine our health, we may be able to ...
