Making an Arduino shield can be simpler than you think. This time I designed one to program Attiny and Atmega microcontrollers, that way I don't have to use a breadboard and make the wiring to program ...

The audio component centers around the SS8550 PNP transistor (Q1) which serves as a driver for the passive buzzer (BZ1). This ...

The buzzer project is quite simple and exciting, as it enables even a newbie to learn how to make use of the Arduino board in controlling the operation of a buzzer. By writing a small program, the ...

We designed a Multi Switch Control Circuit to control a buzzer or an appliance using multiple switches located in different areas.

How does it work? The Arduino Digital Dice is built around an Arduino microcontroller, which serves as the brain of the whole operation. A simple yet clever circuit connects the components seamlessly, ...

Elektor has been publishing innovative design projects and engineering tutorials since 1961. Check out these projects from past June editions of Elektor.

Here you are going to learn how to make a soldering station with temperature controller to control the temperature of the soldering iron especially for micro soldering or any other precision soldering ...

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 during a school ...
