In this lesson we’re going to check out the Sound Sensor Module, aka, KY-038 (perhaps wrongly identified as KY-037). I’ll step through the Elegoo provided tutorial, briefly explain the code, and build ...

For example, if the object is 10 cm away from the sensor, and the speed of the sound is 340 m/s or 0.034 cm/µs the sound wave will need to travel about 294 u seconds. But what you will get from the ...

In this article, we discussed the hall effect sensor module, its working, pinout, types, and also how to use it with Arduino. Here you can find Circuit Diagram, Complete Arduino Code, and a ...

Arduino Hall Effect Sensor Working: Once you are ready with your Hardware and Code, just upload the Code to the Arduino. I have used a 9V battery to power the whole set-up you can use any preferable ...

Electronic systems can help the visually impaired. This project combines an Arduino Nano, a TCS34725 color sensor and a buzzer to assist color blind users.

They’re using a cheap sound sensor module and an Arduino to catch instantaneous photographs, with students caught in the act of popping balloons.
