A Faraday Cup is an instrument used to detect and measure the charge of a beam of charged particles (ions/electrons). When the beam hits the isolated metal cup, it accumulates charge which produces a ...

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.

Every code here should run on every arduino board without problems. The sketches rely solely on the tone() function from Arduino, so the sounds are all monophonic. On the bright side, libraries are ...

Figure an Arduino most matches the "Other" category. To be specific, it isn't an Arduino brand, it is a DigiSpark, but the trouble isn't with the device itself. The problem is with a buzzer. I got the ...

The FM receiver module is based on the TEA5767 [1, 2] chip. It is a well-known module that could be controlled via the I2C bus. It covers the FM frequency range from 76MHz to 108MHz. At the output, it ...

A DC motor can be switched ON and OFF using this amplifier circuit while being able to regulate its spinning speed with a PWM source generator. The circuit is using the pin 9, 10, and 11 from the ...

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 ...

Runner and Arduino enthusiast Nikodem Bartnik has created a DIY 100m sprint timer which is placed at the finish line and signals the start of timing via an audible bleep from its integrated speaker.
