DIY Arduino Holographic Matrix Clock

This project is sponsored by PCBWAY www.pcbway.com...
This is another in my series of unusual DIY clocks, this time realized based on the holographic effect. This is the simplest way of creating a hologram, where the light source and the screen are placed at an angle of 45 degrees.
The clock is really simple to build, and consists of several components:
- Arduino nano microcontroller
- DS3231 Realtime clock module
- 8x32 Led matrix module
- and two buttons
It can also displays holograms from a smartphone. The entire device is covered with black matte wallpaper, in order to have as little reflected light as possible on the surrounding parts, for a more realistic appearance.
Detailed instructions, schematic, and code at:

what kind of reflection plastic thingy is that just asking

[@MirkoPavleskiMK]

1.5 mm plexiglass

[@cadcoke5]

To help hide the idea that this is a reflection, I would suggest adding some metallic framework around it. It may help if that metal is somewhat random and angled around the sides, and if the glass is not just a square, but somewhat angled on the sides. The goal would be to suggest that the surrounding framework is generating the fake hologram.

screen is 45 degree but what about the led panel? on which degree its facing the screen? thank you!

[@markawbolton]

Love it... would like to build one... go with my nixie clock..I am thinking of how to incorporate it with existing furniture. As to double imaging when using thick glass - is it possible to partially silver the front surface so the second image is not so prominent and just looks like a faint echo? I suppose you want o have the screen as inconspicuous as possible - or maybe not - perhaps doped rice paper? X Ray film? lots of possibilities..

Amazing...😍
May I try and ask for permission to use the program code, Sir?
😁✌🙏

[@MirkoPavleskiMK]

Of course, you can also modify it if you want

Thank you very much for your permission and response🙏
I've tried it, but the big number only says GF:HJ
what should I do to match the clock so that it runs normally
🙏

Видео за мерак, интересен проект. Од кој материјал - плоча ги изработуваш кутиите?

[@MirkoPavleskiMK]

Fala, od PVC tabla 3mm i 5mm, ja nabavuvam vo firtma za izrabotka na svetlecki reklami

[@xaero7262]

is it possible to provide libraries because Arduino ide 2.0 lib is having compiler issues

[@MirkoPavleskiMK]

You can now download the libraries I used on Hackster www.hackster.io/mircemk/diy-arduino-holographic-matrix-clock-c35b5e

@@MirkoPavleskiMKThanks i've got 1 last issue my text is mirrored instead of hello! it displays !olleh how can I change? edit bcs I'm not using the glass so I don't need it to be mirrored

[@MirkoPavleskiMK]

Try in this part of code:
if (val == 1) {
// lc.setLed(address, y, x, true);
lc.setLed(address, 7-y, x, true);
} else {
// lc.setLed(address, y, x, false);
lc.setLed(address, 7-y, x, false);
to activate commented rows instead current active rows
