This device should count and indicate how long my hamster runs for a day. When she runs over 2 miles a day, she will receive a treat. A magnet is going to be attached to the outside of the hamster wheel, and when the wheel rotates once, a hall effect sensor will sense it and count once. Using the inner perimeter of the wheel I can calculate how many turns equals to 2 miles.
An LED is also needed for indication of functioning.
When she reached the goal, a servo with food will rotate and drop off food into her bowl. This will help solving the problem because the mechanism will motivate her to run more.
Is this a good/useful/informative piece of content to include in the project? Have your say!
