I entered the wrong email address.
Thank you for this DIY project.
Is the programming switch a push button or a switch? Is the pin permanently grounded when the watch winder is running?
Thank you in advance.

Greetings Brett, Enjoy the LED Wordclock. I made it with a fully 3d printed front diffuser. Printed it on a Bambu with an AMS for two colors. I would be happy to share it with you if you wish.

I do not have a local NTP and it appears one is required to have the clock update each minute. Also, the seconds display along the bottom does not work. It appears to be stuck on the seconds when the clock reset.

The RTC synchs and sets the clock when reset by power or 2 second button push but does not update the time while running. I selected animations and seconds update on the website when I set it up so I would expect the seconds to update.

Any help would be appreciated. Thanks.

Hi Brett,

Just wanted to say thanks for your word clock instructions and the Arduino code you share on your site. I built mine a bit different, but the basic elements are the same. For the front panel, I used an aluminum sheet, 1/8" (~3mm) thick and 4 ft (~1220 mm) square. It's big! I might be pushing the limits of the MAX7219 chips as I am running 2 LEDs to each letter. Each LED is 20ma, so I've configured the drivers for 40ma per letter. I didn't want to guess which resistor to put on the LED driver boards, so I ended up putting a 20k ohm pot to adjust if needed. One issue I ran into with such a large clock was diffusing the light from the LEDs so that there was no "hot spot" visible behind each letter. I ended up making an acrylic tile for each letter and mounting the LEDs along the perimeter of each tile. It was quite a bit of work, but worth it in the end. I'd love to share some pictures with you - not sure how to do that here?

Thanks once again,
Kevin

Hello Brett,

I am currently building the “Basic” version of the Arduino Word Clock (4 x DOT matrix, Arduino nano, RTC module) and am waiting for the remaining components.

I am using the latest version suggested on your website, which is 4.6.

Word Clock display – OK, digital clock display – OK, analog clock display – oops – minus 1 hour.

In which of the 30+x files can I make a small necessary correction?

I am looking forward to the next steps in your detailed building instructions. Thank you for all the effort you have put into this one clock (and there are so many others from you).

Is there already an idea to port the program code to an ESP32? With the WiFi available there, external synchronization and the switch for summer/winter time change would no longer be necessary.

Best regards,

Andreas
