Also, this module focuses on how to time events using Arduino’s built-in function millis (). It is designed to be used with a pre-built ramp that can be provided if used in a classroom environment.

AnalogWrite uses the various timers on an Arduino to put out a pwm waveform – with 1/256 (ish) resolution. And it offers 0% and 100%. This is naturally-available with the timers that the Arduino IDE ...

Makers, Arduino and electronics enthusiasts that have wanted to create a laser sky effect generator, may be interested in this new DIY tutorial which ...

Droplet and StackAR, developed by MIT’s Media Lab, allow users to set timers or program an Arduino using light-based communication. By pressing the tool against a screen, flashes of light can ...

Arduino enthusiasts and makers looking for a project to keep them busy over the next couple of weekends might be interested in this Arduino flying start lap timer, which has been featured over on ...

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer.

The Arduino part is responsible for the steering of the lens and taking the LDR readings. This information is then sent to Processing which takes care of interpreting the data and translate it to ...

[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… ...

This module shows how the Arduino can be used to time physical events. In this case, we measure the duration of a passing object when it breaks a light beam. If the object has a known length, such as ...

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.
