Candy dispenser

I aimed to make a touch-less candy dispenser using arduino uno and an IR sensor.

I looked around for reference to build one in the hopes of learning arduino, but all the dispensers were a single time use and did not have a storage feature. Thus, I began designing my prototype with a storage chamber on the top that funnels the candy down to a small canal. A sliding lid on the top helps cover the top once we are done refilling.

The IR sensor detects the object (hand) and makes the servo motor rotate, thus rotating the arm and dropping the candy through the hole. An extra piece of cardboard holds the rest of the candy in the canal when the arm rotates to drop the candy.

This project gave me a basic understanding of how arduino works with sensors and how the coding is to be done.
