Binary Clock v2
Final version of my binary clock. The original design had the PIC chip controlling the display and doing the timekeeping, however, this was unreliable and the clock gained about a minute a week. This design uses a realtime clock chip and the PIC chips reads the time from it every second over I2C, this has the advantage of being able to use a backup batery to keep the time even when the power is disconnected, although I am not using this feature in this circuit.
