Some of the first steps toward working with Arduino is understanding how to write code for it. The good news is that it's made with beginners in mind.

Replacing the original controller is an Arduino Nano running Grbl, likely giving this revived laser cutter better compatibility with popular open source tools than it had originally.

An Arduino can measure time, a coil and a resistor will create a delay proportional to the circuit values, and metal around the coil will change the coil’s inductance.

YouTube channel How To Mechatronics has created a great tutorial with full instructions on how to create your very own Arduino powered 3D wire bending machine.

The Arduino mini lazer paper-cutter has been under development for some time by Instructables user “kokpat” whioc has now finished the project and posted its details on the Instructables website.

Laser cutters are great DIY tools, but they're pretty expensive. If you'd prefer to build your own, Instructables user SilverJimny shows you how using an Arduino. The build here uses an Arduino ...

Well tech tinkerer Joe Desbonnet has whipped up what he dubs "poor man's NFC" using an Arduino, some magnet wire, and any compass-equipped Android smartphone (which is almost all of them).
