Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

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 ...

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sensors ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. [Udo] hit upon the idea of pulsing a laser pointer and measuring the time of the ...

Arduino, the open-source hardware, software and content platform, has collaborated with Chinese DIY electronics company, Seeed to create the Arduino Sensor Kit. The kit brings Seeed’s Grove sensors to ...

This week I will outline a project for Halloween that uses the Arduino and a light to create a glowing effect inside a pumpkin. I use artificial pumpkins for projects like this so I can reuse them in ...

Arduino has announced the official release of Arduino IoT Cloud, an “Internet of Things Application Platform” enabling you to easily develop and manage IoT apps. The system first emerged back in ...
