When reed switch is opened, pin 2 of Arduino goes high with the help of the pull-up resistor R2, and the alert signal is available through the piezo-speaker PZ1 (not an active piezo-buzzer). At the ...

PANIC ALARM - ARDUINO // // by T.K.Hareendran // int rlyPin = 12; // Relay Output Pin int sensPin = 2; // Switch Input Pin int ledPin = 13; // LED output Pin int pzSpeaker = 10; //Piezo-speaker Output ...

While the pinout is very similar to the Arduino Nano’s ... audio is also provided in the form of a piezo buzzer that can be muted with a slide switch. It can be programmed to play beepy tunes ...

[IngGaro]’s latest project uses the full range of features available in this versatile microcontroller and has turned an Arduino Mega into a fully-functional home alarm system. The alarm ...

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 Velleman svm06. It says it is rated at 3-7VDC ...

Sabec, the studio that turned Nintendo Switch into a scientific calculator, is back at it with another pretty ridiculous app for the console. Spy Alarm creates an invisible beam using the infrared ...

Buzzer: An audible buzzer provides an additional layer of feedback, alerting users to test results. – Library for Arduino: The shield comes with a dedicated library for Arduino, simplifying the ...

[Drive Science] hopefully took one step ahead though and added a decoy killswitch instead which triggers the alarm. The decoy switch is placed near the steering column, where it would easily be ...

A Switch 2 announcement? Oh, Nintendo's got a hardware announcement for you, all right: the fancy little $100 alarm clock it launched last year is coming to retail. Yes, Alarmo – previously ...
