This example code wakes the onboard indicator (LED at D13) of the Arduino when a tilt is inputted by the tilt sensor module through the occupied digital input (D2). Just copy-paste this code into your ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy ...

With just a little bit of code, this 3D tilt sensor becomes a six-way switch to control an RGB LED. Video of that below.

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...
