301 LED Analog Clock Project Schema Files of PCB and C51 Compiler Source Code has been prepared by the C-in hex
The clock circuit is made of 301 LEDs with a diameter of 3mm forming fi = dial (the most one LED is in the middle), and 12 LEDs Stroke hours. The LEDs are arranged in seven zones. The three most outer rings comprise 60 LEDs each, and four inner circles each comprise 30 LEDs each. It was dictated by the size of the clock, which size is similar to the size of a CD, which shows the photograph above. Just the size of the clock made the four inner circles not accommodate the full amount of 60 LEDs. However, I used a trick here: namely, control LEDs is done in such a way that the diodes in the inner circles light up alternately with the movement direction. The final result is more than satisfactory.
