This project implements a simple alarm clock using an Arduino, a DS1307 real-time clock (RTC), and a buzzer. The current time is displayed on a 16x2 LCD screen, and an alarm is set to activate the ...

Reads the analog temperature sensor every 100 ms. Converts analog value to temperature (°C). Stores it in a shared variable currentTemp protected by a mutex. alarmTask Checks the current temperature ...

Here is a simple general-purpose security alarm circuit built on the Arduino platform. It brings up an obtrusive alert signal when an intrusion/theft attempt is observed by its front-end sensor. In ...

Here is the circuit of an Arduino-based Panic Alarm! The wiring is very simple so that even a novice can construct this interesting circuit without any difficulty. Arduino is a family of ...

Abstract: In recent years, with the increasingly serious problem of environmental pollution, the demand for real-time monitoring and early warning systems in homes and industrial places has been ...

Blinking LED: The classic "Hello, World!" of Arduino is the blinking LED project. It introduces you to the fundamental principles of writing code, uploading it to your Arduino board, and seeing ...

Keeping track of things like the temperature, humidity, and smoke level in your house is important. If you want to make your own system for doing so, Instructables user ICStation shows off how to use ...
