“Arduino Self-Timer” project presented here is a low-component count 60 seconds countdown timer. It can be powered from a 9V compact battery or suitable Arduino AC mains adaptor. Working of the ...

The Arduino ecosystem is an amazing learning tool, but even those of us who love it admit that even the simplified C Arduino ...

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 ...

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.

[Scott-28] recently sent in a particularly well-documented project that turned an antique rotary phone into a digital kitchen timer using an internal Arduino.

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 ...
