This isn’t a true LED matrix. Instead it combining all of the LEDs into a common Anode, since the Cathodes are all controlled by individual outputs of the TLC5940. I decided to wire up 16 LEDs, even though a binary clock only needs 11 or 12. This gives some flexibility to other uses for the box, like a random sci-fi computer pattern.https://www.baldengineer.com/accurate-rtc-shield-rev2.htmlSun, 08 Jul 2012 00:02:39 +0000https://www.baldengineer.com/?p=935Accurate RTC Shield with Kapton Stencil For the past couple of weeks I have been working with the DS3231 Maxim. This chip is a I2C based RTC with an integrated temperature compensated oscillator and crystal.This means despite changing temperature conditions, it will maintain a very accurate track of time. If you’re interested in the first rev of the PCB, let me know. I have a few available. They are functional, however, the prototyping area came bad.I have a set of new ones with a proper prototyping area, reset button, and power LED in process.https://www.baldengineer.com/accurate-rtc-shield.htmlTue, 29 May 2012 03:32:24 +0000https://www.baldengineer.com/?page_id=867Status: In Progress, Last Update: October 14, 2012 GiHub: https://github.com/jamesc4s/Accurate-RTC-Shield Abstract The DS3231 is a Precise Real-Time Clock from Maxim. It requires almost no external components and is temperature compensated. This chip solves some of the RTC issues associated with the DS1307. This Arduino shield will make it simple to add a RTC to any project, especially one where lost time is not acceptable. Electronics Parts list:
