Animated Pegboard Clock using 625 LEDs
Evil Mad Scientist, who make the Peggy 2 LED board ran a competition to design a clock using the Peggy. I proposed a subtly moving view of an analogue clock (borrowed from Victoria station in London) that follows the minute hand but shows enough of the face to see the hour hand too. I won the Peggy with my design, so decided to implement it.
It took me far too long to get it going but I have a sparkfun RTC DS1307 (dropping 5 minutes every month, avoid!) telling the [arduino compatible] onboard atmel the time. The code and image are all held in the IDE’s compilation of my probably pretty inefficient code, and it is on the limit of not working; One more variable and the stack hits the heap and it stops working.
Still, shows off what can be shown on a 25×25 2-bit greyscale display like the Peggy, and illuminates my living room enough to not stub my toes in the dark too! ….Simon
