3D clock

Some text some message..

This is an nice application using Annex and its internal support for the MAX7219 dot matrix display.

The design is based on the original project that can be found here

The case can be just be printed using a 3D printer.

The 3D printer .STL files can be downloaded here

All the instructions on how build the 3D case can be found in the original project.

The software is just annex and few lines of code.

The electrical wiring is the one already present in the documentation

This example shows only the date and the time but it can be modified to show many other information such as weather, news in addition to local information as temperature, humidity, etc.

At the bottom of this page, there is another example that adds the weather information.

The code is very simple
