Software developer John Montgomery has experimented with an Arduino board, an inexpensive doorbell and a variety of odds and ends to come up with what he has termed the "Ultimate Arduino Doorbell". Perhaps the title is subjective, but John has documented his exploration from the start, culminating with a wireless doorbell that rings an actual bell using a servo driven by the Arduino. Here it is in action:
Apart from resulting with a different doorbell, it's always interesting to watch how people experiment and discover. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
When making your own doorbell or other project, increase reliability and project lifespan by using a protoshield instead. In doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega range, we offer a complete range for you to work with.
