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 ...

The experiment is for switching an acoustic sounder as a rain alarm after a predetermine time. It may, however, be tinkered for a number of other applications. Needless to say, this is a simple ...

The code for this project is written in the Arduino programming language (based on C/C++). It uses the digitalWrite() function to control the state of the LEDs connected to the Arduino pins. The ...

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]’ ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

Walking safely and confidently can be a challenging task for visually impaired individuals, but with the help of technology, we can make it easier for them. This DIY Blind Stick is an innovative yet ...

Arduino, the open-source hardware, software and content platform, has collaborated with Chinese DIY electronics company, Seeed to create the Arduino Sensor Kit. The kit brings Seeed’s Grove sensors to ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...
