RingbellI have designed, developed and built this little ringbell system for our shared office in Berlin-Kreuzberg. Using Arduino and servo motors to make these brass bells found on a fleahmarket ring when somebody comes to visit us. Since there are 2 Rooms on our office, i developed 2 modules that can be activated by different buttons. The mechanism is quite simple, pressing the button makes the arduino tell the corresponding motor to pull from a small thread that makes the ring bell, it can be considered as a Digital-to-Analog artifact and the result is really natural. Way better than a cheap Buzzer! | ![]() Bell 1 | ![]() Bell 2 | ![]() Bell 1 - Detail | ![]() Bell 2 - Detail | ![]() Button box |
