7 SEGMENT CLOCK ON OLED DISPLAYS - PART 3

This project was developed together with a friend and is very well presented here:

My friend came up with the idea, drew the scheme, wrote the sketch, printed the case and performed the final assembly and my contribution was the design and realization of the PCBs, the design of the case elements.

This project has three parts:

- The elements of the case - 3D printing project, this project

- PCB for WEMOS D1 Mini, you can find the project here:

- PCB for the 4 OLEDs, you can find the project here:

To realize the entire project, all the components described in the three projects above must be used.

The clock works very well and is very accurate because it is permanently connected to an NTP server. There is the possibility of setting winter or summer time, as you wish, by activating a switch on the back of the case. Powering the watch can be done with any 5V DC source, but it works very well with a mobile phone charger.
