The newly released Arduino Leonardo has a few very interesting features, most notably the ability to act as a USB keyboard and mouse thanks to the new ATmega 32U4 microcontroller. This feature isn&… ...

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.

[R-B] designed a 555 timer circuit to scan a keypad. Keypads are common interfaces for small projects and require row and column scanning by a microcontroller. [R-B’s] setup allows you to red… ...

Time is calculated using the GPS, which sends out a line of ACSII data; the Arduino waits, and receives the data that reports time and date. Instructables offers a more intricate break-down 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 ...

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 ...

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. The ...

Timing parts of an Arduino programme (‘sketch’ in Arduino-speak) tend to use this clock as a reference. While the majority of Arduino projects seem only to be on for a few minutes or a few hours, some ...
