The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

You’ve doubtless seen those ubiquitous clock modules, especially when setting clocks for daylight savings time. You know the ones: a single AA battery, a wheel to set the time, and two or thr… ...

1. Arduino Nano Microcontroller: This small yet powerful microcontroller will be the brain of your clock, handling all the logic and control for the LEDs. 2.

Alarm clocks are cheap and abundant, but they’re pretty boring. If you want to make your own, Instructables user Paranoid Legend shows you how to build one with an Arduino.

Instead, Make shows you how to build an internet-connected alarm clock using an Arduino and Google. All you'll need is an Arduino Yúnm a touch screen, a USB speaker, and a few cables.
