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 microcontrollers have added Python to the range of compatible programming languages. Others can be used, and not just Arduino's own IDE app.

An Arduino timer answer, probably. 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 ...

[Chris] wrote us to share a neat technique he has been using to program the Arduinos he uses in his projects. He likes to build bare bones Arduino clones rather than sacrifice full dev boards ...

When notes stuck to the water heater failed [Ryan] decided to whip up “the world’s most expensive 240V relay” using a servo, a real time clock and of course an Arduino. All in an … ...

This module shows how the Arduino can be used to time physical events ... The presentation material and the code can be downloaded at Derby Timer.

We’ve featured a lot of interesting DIY timepieces in the past (most recently this Arduino Sesame Street ... as using a timer to brew a mug was the inspiration to create it in the first place.
