Arduino Buzzer Circuit

This article and circuit diagram show how to connect a buzzer to an Arduino when the buzzer operates at a different voltage to the Arduino. The buzzer may operate at 9V, 12V or some other voltage. Arduinos such as the Arduino Uno operate from 5V. All the voltages referred to here are d.c. voltages (direct current). The same circuit used here can also be used to operate a 5V buzzer when the buzzer draws more ...

Arduino quiz show buzzer

A good friend of mine who's a teacher was doing quizzes in her class making students compete to answer questions... resulting in them complaining they raised their hands before the others. I decided to give her this quiz show type buzzer for Christmas to solve her problems. When one of the players press it's button (the fastest player wins this), the led of the right colour lights up saying he's in control. ...
