As someone who frequently bakes, a common issue I have is not realizing when I've used up an ingredient. To combat this, I decided to create something that notifies me when an ingredient is out. I did this by creating a giant "button" with a metal touch sensor that e-mails me when a food item of my choice has not been replaced on it for a certain amount of time.Video:IFTTT Setup:

Using a metal touch sensor, I've essentially made a button that notifies the user when it's been released over a certain time threshold.
