I have been delving (groping blindfold, more accurately) into the Arduino compiler adaptation code to try to determine how it handles the switch-over between its pwm activities, its set-I/O-to-output ...

“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 ...

We’ve featured a lot of interesting DIY timepieces in the past (most recently this Arduino Sesame Street creation) and the community keeps on creating new ones. Andy Evans, who goes by the ...

You could put the Arduino in deep sleep, if you wanted to and that LED will still blink. With a little work, you could probably adapt this idea to any number of circuits out of the 555 playbook ...

[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.

You have a timer and clock in just about every single device out there these days, but if you want to build you own, Instructables user GeraldF6 shows you how to do so with a Arduino. The project ...

The programmable timer features and up counter, down counter, and point accumulator that can be programmed manually using only one on-board button, or digitally with your Arduino or Raspberry Pi.

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 ...

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 ...
