Make your own Arduino Word Clock

Building a clock is almost a rite of passage in the Arduino community, and Arduino forum member Riva has certainly moved forward and created a great word clock. Using 128 LEDs, a lot of prototyping board, and a non-board Arduino circuit using a pre-programmed microcontroller, the results are very good. What finishes the clock well is the housing and the quality of the laser-printer clock face. And unlike other simple word clocks, the display can become one large scrolling text unit as well. Here is the clock in action:


Kudos to Riva for their excellent clock. For build and design instructions, head over to their forum post. And for more, we’re on twitter and Google+, so follow us for news and product updates as well.


For your own projects that require working with real time and date – consider using our super-accurate real-time clock module. Based on the DS3232, it has a temperature-controlled crystal oscillator for accurate time keeping, battery backup and 236 bytes of non-volatile memory for user data.
