I design parking sensors using arduino uno together with ultrasonic distance sensor, buzzer, and leds. Bu projedeki temel amacım arduino uno kartı kullanarak HC-SR04 ultrasonik mesafe sensörü, buzzer, ...

For-fun experiment with an Arduino UNO, where a passive piezo-buzzer’s pitch is controlled by an ultrasonic sensor (HC-SR04). The whole idea of this “pseudo-theremin” is to obtain the proximity to the ...

A buzzer has two pins, namely positive and negative. The positive terminal is represented by the ‘+’ symbol and negative terminal is represented by the ‘-’ symbol just like an led and a capacitor.

Nowadays, sensors play a major role in the safety and security of many different apartments, homes and offices by detecting smoke, fire, or gas and providing an alarm to the concerned person. That is ...

Planning a game of Hacker Jeopardy at your next meetup? You’re going to want some proper buzzers to complete the experience, but why buy when you can build? [Flute Systems] has released an open source ...

Abstract: The paper aims to design and implement a low cost and reliable quiz buzzer system with the help of Arduino and seven segment display for easier detection of contestants or participants ...
