As many Arduino enthusiasts will tell you, they have a million ideas for projects but haven't completed nearly as many as they want. Here are some of the best Arduino projects we have found.

Jon Bumstead has created an awesome Arduino powered 13 note midi harp after receiving funding from the optics group Spectra at Washington University in Saint Louis.

Makers and developers might be interested in this new project which has been published by Instructables user “Venkes”, who has created a DIY laser scanning microscope using an Arduino Uno ...

Dubbed the “Cat Laser Tower”, the build consists of two servos to move the laser about, some 3D printed housings to hold them and provide pivot points, a small laser and an Arduino to make ...

In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk.

[over9k] used his Arduino to set up a laser trip wire. The laser is mounted along side the Arduino, reflects off of a mirror, and shines on a photoresistor that interfaces via a voltage divider. Th… ...

There are approximately a zillion DIY laser engraver tutorials on the Web, but of all the homemade builds we've come across, this one from Instructables user MichielD99 is definitely one of the best.

Laser Blaster Last Updated: 7/27/18 Teaching Standard: In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates ...

As much as we love the Arduino Uno, it's not the most powerful of hobbyist microcontrollers. Fortunately, the folks in Turin have just put the finishing touches on a 32-bit upgrade with buckets of ...

In this series, I will be building a single propeller spherical drone which will be controlled via an Arduino. I have designed this drone in Solidworks 3D CAD software and I will be making all of the ...

He mounted a photo cell in a project box, along with an Arduino and a 12-button key pad. A laser pointer is aimed at the photo cell from across a gap, which results in a steady voltage being read ...
