Put aside all of the projects that use an Arduino to blink a few LEDs or drive one servo motor. [IngGaro]’s latest project uses the full range of features available in this versatile microcontroller ...

When [Doug] moved into his new house, he found an old alarm panel set up — but it had no monitoring service any more. Not wanting to pay a monthly fee to have it setup, he decided to try interfacing ...

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 ...

Dejan Nedelkovski has built a stylish DIY touchscreen Arduino music player and alarm clock which has been created using a folded piece of sheet metal to provide a minimalist yet clean enclosure to ...

As a preview of his latest book, Arduino Project Handbook: 25 Practical Projects to Get You Started, Mark Geddes takes us through the project to create a simple laser trip wire alarm. You've probably ...

Alarm systems are complicated affairs. However, if you’re just looking to catch a sandwich thief at work or a cat spilling over all you water bottles, then Make shows you how to build an alarm system ...

In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

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 ...

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 ...

It’s no Clocky, but this alarm clock innovates in a way that’s charming in and of itself. Rather than just having an annoying buzzer, not unlike the sound of creeping death to wake you up, it has a ...
