What Is It?

The WiFi LED Matrix Clock is a fully assembled, precision digital clock powered by the ESP8266 Wi-Fi microcontroller. With a vibrant LED matrix display, it shows accurate time in real-time seconds, thanks to NTP (Network Time Protocol) auto-syncing. The display can be configured to update digits via traditional transitions or smooth downward scrolling, offering a visually appealing and technically impressive desk or wall clock.

This smart digital clock is perfect for makers, tinkerers, and tech-savvy users who value both functional utility and customizable options. Whether you're building a smart home setup, managing a lab space, or simply need a stylish atomic-style digital desk clock, the LED Matrix Clock delivers reliability and modernity in one minimalist design.

Why Did I Make It?

1.As a maker and electronics hobbyist, I wanted to create a DIY-friendly product that combines.

2.Learning by Building – Working with the ESP8266 and LED matrices gives you a hands-on way to understand microcontrollers, NTP protocols, and web configuration systems.

3.Internet-Powered Accuracy – WiFi NTP sync ensures your clock is always accurate, even during daylight saving time transitions.

4.Everyday Utility – It functions not just as a tech demo, but as a useful, reliable, and sleek digital LED clock.

5.DIY/Tech Community Love – For fellow Tindie makers, this clock is programmable, expandable, and easy to integrate or modify.

What Makes It Special?

Precision Timekeeping with NTP Sync

1.Syncs with NTP servers via WiFi to deliver atomic clock-level accuracy.

2.Custom NTP server address supported, allowing advanced users to specify their preferred time source.

3.Time zone and DST auto-adjust options for global usability.

Custom Sync Frequency

Choose how frequently the clock connects to the NTP server (e.g., every hour, every day), giving you control over network traffic and accuracy.

Dynamic or Static Time Display

Users can choose between two display modes: Static digit change (classic style) Scrolling down transition (animated drop effect)

Show/Hide Leading Zero

With our latest update, you can now choose to display or hide leading zeros (e.g., 08:00 or 8:00), based on your personal preference.

Manual Time Error Correction

Includes a calibration feature to manually correct small time drifts.

Note: After each correction, the value must be reset to 0, and the device rebooted to avoid compound errors.

12/24-Hour Format + Date/Week

Switch between 12-hour and 24-hour time formats.

Full support for day of the week and date display, making it useful for any desk or bedside setup.

WiFi Setup Made Simple

Configuration via local web interface using:

Hotspot mode (before WiFi setup)

IP address (after WiFi connected)

Select from 24 time zones, with auto DST toggle.

Secure Hotspot Disable

For enhanced network safety, users can disable the device hotspot after WiFi setup to prevent unauthorized access.

Adjustable Brightness & Auto-Rotate

10-level manual brightness adjustment.

Built-in gravity sensor allows automatic screen rotation for horizontal or vertical use.

Fully Assembled & Plug-and-Play

No need to solder or flash firmware. Just power it on, configure via the browser, and you’re ready to go.

Powered via standard USB port (5V input), making it compatible with PCs, power banks, or any USB adapter.
