This is a candy counter for halloween made with an Arduino nano with enhanced features like sound and light effects every time a candy is detected. This is powered by a 2600mAh power bank and thanks to low power configuration halloween candy counter can run all halloween night.
The number of collected candies are showed in a 16x2 lcd screen.
All electronic staff can be inside your favourite halloween candy bag, in my case a plastic halloween pumpkin used by my son.
