Berlin Clock (BerlinUhr)
thingiverse
This is my first major project, combining 3D-printing and some electronics. More information about Berlinuhr can be found at https://en.wikipedia.org/wiki/Mengenlehreuhr. Parts list and source code: 1. Arduino Mega 2. ds1307 rtc arduino 3. DCF77 Receiver 4. 13 x 5mm LED's 5. 8 x 3mm LED's 6. OLED-display-modul 128X64 I2C LCD-screen board, 0.96" SSD1306 7. some cables, screws, soldering station, resistors for the LED's 8. sketch for Arduino (attached in the docx) After reviewing the code, it should be clear how the LEDs and RTC, DCF77 module are connected to the Arduino board, so I did not include a circuit diagram.
