[Kyle] plans on a follow up tutorial to cover timer based interrupts, which can come in handy when generating frequencies and stuff. Looking for more Arduino Basics? How about Basic on an Arduino.

If you're looking to make yourself somewhat more productive on this lazy weekend, and you've got an Arduino or two collecting dust, we've got just the thing to add line after line to your ...

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 ...

Sometimes you don't need a large microcontroller to get your work done. In this installment, TK teaches us how to use the ATtiny combined with Arduino to use the PWM function found on this chip.

The AvecSynth takes this IC and puts it in a standard Arduino-sized package so building a gigantic light-up, foot-operated piano is now well within the purview of the weekend solder junkie.

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.
