A project I have been working on has finally come to be near complete. As a gift, I build a custom clock using an arduino, a Chronodot RTC, some bi-color 8×8 matrix displays and some other random parts. I hope to post the details soon. Till then, some pics:
The matrix displays will do green, red and amber. The reason for the display choice was color. They match the team colors. The display color is set via a button on the side, and at the roll of the minute the top 4 displays show a color correct U for 10 seconds.
Functions working are time, color change, auto dimming and sounds (beeps for control input). Functions to be compeleted are alarm, score (it is a score clock after all) and timer.
