For groups, clubs and other smaller organisations that require a simple yet accurate voting system, the following Arduino-based solution by Frank Donald will solve the problem. His system allows for four possible candidates, and each voter may only vote once.
With a little supervision the system works well and the results can be displayed in the Arduino IDE's serial monitor, or with some modification a connected LCD. Frank runs us through his voting system in the following video:
As always if you want to modify this to meet your own needs - this can easily be done. However for complete details, visit Frank's detailed website. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
