Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

As photons (light) land on the detector, the resistance will decrease. The more light is we will have a lower resistance. By reading different values from the sensor, we can detect if is it light , ...

[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.

GitHub - Geovane-ss/arduino-alarme-i2c: Sistema de alarme com dois Arduinos Uno usando comunicação I2C, sensor PIR, buzzers e LEDs. Alarm system using two Arduino Uno boards via I2C with PIR sensor, ...

[Paulo’s] garden lights are probably a bit more accurately automated than anyone else’s on the block, because they use latitude and longitude clock to decide when to flip the switch. [E… ...

A LED display fan clock made using a thin strap of PCB board connected with various components like LED lights, Resistors, capacitor, Hall Sensor etc. to be rotated on a DC motor to display Time using ...

The Arduino uses latitude and longitude to help decide when to click on the lights, so it's incredibly accurate. Otherwise, the build just includes an on/off switch, a Tiny RTC, a time adjustment ...

Essentially, it is another safety initiative that gives a visual warning of a biker braking, with LEDs tucking up the end of the handlebars. It is based on an 3-axis accelerometer board, provided by ...

LPG is an alternative fuel used for daily use. Due to its low cost and ease of installation. This article covers an Arduino-based gas detection system that uses an Arduino UNO R3 board and gas sensors ...
