Alarm clock in tech design - Arduino-based desk clock
But the sketch is very beautiful. With sunset effect.
Anyway. The watch case is assembled from 4 plastic parts printed on such a 3D printer .


What I used:
• Arduino UNO
• MP1095 - Real-time clock (RTC)
• 1.6 "Color CSTN display (132 * 132)
• Three buttons.
• Piezoceramic tweeter.
• 8 M3x16 screws
• 2 M3x45 screws
• 8 simple M3 nuts and 2 self-locking nuts M3
• 3D printer (or you need access to print parts on a 3D printer)
4th plastic parts ( here you can download STL files)
w1 - display platform

w2 - left platform for buttons

w3 - right platform for buttons

w4 - basis for installing Arduino UNO We

assemble the electrical circuit as follows:

Here are the libraries that you will need to compile in the Arduino environment:
ColorLCDShield
DS1307RTC

In the video there are watches made on an acrylic price tag from some store. Also very beautiful!
