This project utilizes an Arduino microcontroller along with an ultrasonic distance sensor to measure distances and provide warnings when objects are detected within certain ranges. The distance ...

This project utilizes an Arduino Nano along with an ultrasonic sensor to create a distance-based LED color changer. The objective is to demonstrate how the color of LEDs changes based on the proxim ...

This Arduino -based distance meter can be used for measuring the distance between the sensor and object in the range of 2cm to 400cm using an ultrasonic sensor. The author’s prototype and ultrasonic ...

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 ...

This is a very simple digital distance meter, which you can add to your water-level indicator circuit to show water level in a tank, or use it for a school/college project. The author’s prototype is ...

Explore a range of Arduino-based DIY projects, from creating contactless thermometers to developing smart home automation systems, obstacle-avoiding robots, and more. These projects offer practical ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...
