Outcome

The code pushes the notification to my smart phone when the stove is turned on through IFTT (left picture). When the oven is on, the LED light starts to get brighter to indicate the duration of the time. After 10 minutes, the beeper is activated to warn the user that the stove has been on for a long time. At any time when the beeper is activated, the user can press the push button to delay the beeping for another 10 minutes (middle picture). This feature allows the roommate outside the house know that there is a person near the stove. Once the stove is turned off, IFTT sends another notification to my smart phone (right picture).
