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 ...

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 ...

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 ...

[linux-dude] always wanted to have a binary clock, but he didn’t want to pay someone else to make it for him. Additionally, he was looking for a compact alarm clock he could take on the road, rather ...

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 ...

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 ...

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 ...
