Arduino

As the preeminent tool for makers, Arduino is a versatile platform that covers almost every type of creative making. With its simple-to-use coding language and fun programming concepts, Arduino enables users to create modern electronics with ease. From beginner level projects like flashing LED lights to more advanced builds such as interactive robots, there are an endless number of possibilities when it comes to building projects with Arduino. Whether you are new or an experienced builder in search of fresh ideas, these posts will provide interesting Arduino tutorials and unique ideas that may spark your creativity and motivate you take on any type of maker project!

Controlling LEDs with Charlieplexing

Controlling LEDs with Charlieplexing

MAKE contributor Andy has created a great tutorial to introduce you to the utility of “Charlieplexing,” a method for controlling multiple LEDs without the use of multiple microcontroller pins. With charlieplexing you can turn on or off one LED at a time. To light more than one LED at a time, you can scan the LEDs by turning a sequence of them on and off really fast.

DIY 3D Laser Scanner Using Arduino

DIY 3D Laser Scanner Using Arduino

The principle behind this scanner is the typical of a line scanner. A laser beam intercepts the object to be measured and a camera, positioned at a known angle and distance shoots a series of images. With some trigonometry considerations and optic laws it is relatively easy to reconstruct the Zeta dimension, the measurement of the distance between the object and the camera.
