Inspired by the Wii Wheel, he imitated a shopping cart handle built from — as it appears — a sunshade pole that holds an Arduino and accelerometer in a 3D-printed case as game controller.

This one only requires about $5 worth of parts and when you’re done building it you’ll have a much better understanding of exactly how the Arduino works. If this particular project is too big ...

It features over 5,400 projects, ranging from simple tutorials — like using a soil moisture sensor with Arduino — to more complete guides like building a Bluetooth-controlled car.

A 3D-printed flying quadcopter drone. 3D printing and flying drones are among the two most popular activities for Arduino owners.Here we have a project that combines both activities into one ...

The sensor can be pointed at an object, and the Arduino can sense the brightness of that one point. In order to compile an actual image, [Jordan] needs to obtain readings of multiple points.

For instance, when you put up both of your hands (one in front of each sensor) at about 40 to 50 centimeters from the sensor, the video is either played or paused.

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this Arduino ...
