This is a smart clock which gives time and weather.

The columns and colors indicate the temperature over a 32h time period (1 column = 1h) and the weather logo shows the trend at +1, +9 & +12h.

BOM:
1x Adafruit Matrix Portal - CircuitPython Powered Internet Display
1x Medium 16x32 RGB LED matrix panel - 6mm Pitch (bought mine on Adafruit)
1x Motion sensor (generic)
1x Black LED Diffusion Acrylic Panel - 10.2" x 5.1" - 0.1" / 2.6mm thick (bought mine on Adafruit)
1x Clear Adhesive Squares - 6 pack - UGlu Dashes
4 M4 screw
5 self taping screw, 3mm diameter

Assembly:

• Trim the back of the LED matrix, there is two small plastic extrusion to cut.
• Bolt the base to the LED matrix via the M4 screws
• Prepare the Matrix Portal as indicated here: https://learn.adafruit.com/adafruit-matrixportal-m4
• Connect the Matrix Portal to the motien sensor. Respect polarity. (The defaut pin for the sense wire is A4) (solder)
• Install the Matrix Portal in the case
• Hot glue the motion sensor to the base. (Adjusting screws must face outside)
• Install the back panel with the 5 self taping screws.
• Cut and install the diffuser panel

Arduino:

• In the arduino IDE, install all the required libraries (https://learn.adafruit.com/adafruit-matrixportal-m4)
• Place the provided .ino and .h files in your arduino folder and open the smartClock.ino file
• Create an openweather API
• Store your wifi credentials and openWeather API in the crendential.h file
• In the main arduino file (.ino) customise the fields under //to customise
• Transfer the program to the board
• The time the display stays on is adjusted on the motion sensor via screwdriver

Have fun :)

Update Feb 5th 2025: I added all the arduino files in a zip folder as printables does not allow to upload .h files.
