🤖️ Ultrasonic sensor with arduino serial monitor The HC-SR04 sensor is a Ultrasonic sensor. we can not use this sensor direct in a circuit. We need a microcontroller for communication with the sensor ...

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 ...

Arduino Processing: The Arduino reads the output from the IR sensor. If the sensor detects an object (i.e., the output is HIGH), the Arduino sends a signal to turn the LED on and then off, causing it ...

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 ...

If you have allergies than you've likely considered picking up an air quality sensor for you house at some point. However, a good air quality monitor will run you upwards of $290.

This Arduino based IR reflectance sensor can be easily modified and adapted for various practical applications, including line-following robots and proximity or edge detection.
