MIT’s Media Lab is working on a system of information-sharing that can use light-based communication to remind you of an appointment or program an Arduino. The coin-sized Droplet is an ambient ...

If you’ve ever seen a mechanical version of an astronomic timer switch ... If you want to make one that doesn’t use the internet, check out this Arduino-based solution that we wrote about ...

I have been trying to work out how to use the the timers within 8bit AVR processors through the Arduino IDE, but in modes not covered by the IDE. Lots of people have put up code, often two or three ...

So we can use a simple formula for routine calculations ... Next is a quick reference card that shows the correct usage of the timers on the Arduino that control PWM outputs (assume an Atmega328 with ...

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.

This Arduino-based Pomodoro timer project also uses this 25-minute ... You're free to eliminate the location part if you're only using one shredder. Aside from the Uno and the ultrasonic sensor ...
