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 ...

Of course he could modify a refrigerator and humidifier to be controlled separately, but [Mike] decided the best course of action would be to control line voltage with an Arduino. [Mike] started ...

For someone who’s never worked with an Arduino before ... There is also a DIP switch that allows the user to select how long the relay circuit should remain open.

The Raspberry Pi is a credit card-sized computer capable of running full-fledged Linux distributions such as Raspberry Pi OS, ...

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go. If that sounds ...
