Overview
BinaryClock is an open-source printed circuit board by tomlonca, from the tomlonca/SnP-BinaryClock repository on GitHub. It is a 2-layer board with 17 parts on 27 nets, routed with 190 tracks and 9 vias.
It is built around the ATMEGA48-20PI. Its parts include 11 diodes, 3 switches, 1 IC and 1 crystal. It belongs with the AVR (ATmega, ATtiny) boards of this library.

This project is about designing and implementing a binary clock using an AtMega48 microcontroller and a custom PCB.
Overview
The clock supports:
- Normal mode
- Sleep mode
- Low power mode
Mode switching is done via three buttons on the top of the board.

Komplexaufgabe
- Bauen Sie eine Binäruhr mit dem ATmega48, benutzen Sie hierfür mindestens die ausgegebenen Bauteile
- Pflicht Features:
- Binäre Ausgabe auf 11 LED’s mit hardware PWM Helligkeitssteuerung (OC1x-Pin).
- Steuerung über Taster (INT0, INT1, x).
- Sleepmode mit Beweis der Reduzierten Leistungsaufnahme nach Datenblatt.
- Zeitbasis über Timer und Uhrenquarz, mit Genauigkeitsmessung, Programmierung über ISP.
- Programmierung direkt über AVR-gcc kein Arduino!
- Sinnvoll wäre es, die Uhr auf der Platine aus HWP II aufzubauen!

Questions
What parts does the BinaryClock use?
17 parts, built around the ATMEGA48-20PI. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the BinaryClock KiCad files?
From the tomlonca/SnP-BinaryClock repository on GitHub, at the commit this page was made from: the board is BinaryClock.kicad_pcb and its schematic BinaryClock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BinaryClock design in my own project?
Its repository states no licence, so its author keeps all rights: ask tomlonca before reusing the design.
