With this project I wanted to make a clock, showing hour, minutes and seconds on the sure3208 Led matrix Display. Because it is only 32 pixels wide, It would not fit time using the font included with the HT1632 library.
So I made my own very small font (only 3 pixels wide). Because a lot of letters and symbols don't fit a 3 pixel wide font, you can only use it for showing numbers. 0-9 end the : symbol.
I used an Arduino Ethernet, because it gave me connection to the internet. This way I can use NTP for updating correct time. You could also use an RTC1307 chip with battery for correct time.
