Need something to keep you busy this weekend? Look no further. The Weekend Workshop is our weekly column where we showcase a badass DIY project that you can complete with minimal skills and expertise.

This module allows you to develop a timing system, which utilizes the Arduino’s fast internal clock to provide an accurate timing system for kinematic experiments. Also, this module focuses on how to ...

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 (blasts) the target using an inexpensive laser diode ...

A laser projector creates a light show that seems to be coming from dozens of laser beams. It only needs a single laser beam to create the effect because the beam is diffracted as it emerges from the ...

In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk. This is ideal for making a toy for your cat or dog. #ArduinoProject #CatLaser ...

Figuring out how to keep pets entertained can be quite tiring. No, you don’t really feel like playing catch with your dog after a long day at work, or dangling strings in front of your cat to stop ...

[Robi] and [Kathy] from elecfreaks have put together a how-to article about a Laser Piano they just built. Instead of keys, the user breaks beams of laser light to trigger the sounds. Several laser ...
