Thanks to Luc for sending in this project! Luc writes:
made a clock that displays the time in color codes. More explicit in resistor color codes.
I used an Attiny85 for this so the project could easily be done with a trinket.
Unfortunately Adafruit products are not easily to come by here in the Netherlands otherwise I could have done it with a trinket……
The color codes are presented by 4 neopixels. 2 pixels for the hours and 2 pixels for the minutes.
Time can be set using 2 pushbuttons.
The clock runs for about 8 hour on AAA batteries which can easily be exchanged for a small USB powersupply.
