Features

• Invisible capacitive touch buttons for user input.
• Automatic brightness control via ambient light sensor.
• Night mode, turning off the display when the room is dark.
• Serial passthrough for updating the real-time clock (RTC).

Fixes and Updates

[!IMPORTANT] This project is currently under development undergoing a major code refactor. Please bear with me while I work on improving functionality.

Hardware and Setup

Laser Cut Housing

All laser cutting files can be found here.

Please insure that:

• The LED diffuser is cut out of white acrylic.
• The clock face is cut out of a thin and opaque material.
• The bottom and sides are cut out of an opaque material.

Doing so will ensure the clock performs at its best.

3D Printed Framing

The 3D printed components will not be visible from the front of the clock, so do not worry about surface finish or colour. However, several of the prints will have to be paused throughout the print to insert embedded fasteners.

Printed Circuit Board

The gerber files for PCB manufacturing can be found here.

Code

Dependencies

This project requires the following external Arduino libraries, please ensure that they are installed:

• FastLED (v3.10.3)
• RTClib by Adafruit (v2.1.4)
• CAP1188 Library by Adafruit (v1.1.3)

For programming of the Raspberry Pi Pico W via the Arduino IDE I've included the board library I used here:

• Arduino Pico by Earle F. Philhower, III (v5.6.0)

Open the Arduino IDE, install the code and board libraries mentioned above, plug in your mainboard, and upload the code.
