 Observation Project MTA MetroCard Kiosk Context:  The MetroCard kiosks I observe are located near the entrance to the Jay Street - MetroTech train station. They are used to purchase, refill, or check the balance of people's MetroCards. The machines have a touchscreen interface, allowing users to select their desired transaction, choose a language, and input payment information (cash, credit, or debit). Assumptions:  Before observing people use the MetroCard machine I assumed that most of the people that used it would already be familiar with how to use it and complete the transaction pretty quickly.

Since some machines only take cash and some take both cash and card, I also figured that some transactions might take longer than others because the machine may need to count bills and dispense change.

 Midterm Project Stress-O-Meter Finished product successfully measures the user's stress level using their heart rate in beats per minute, and depending on the rate will light up an LED as well as play a sound. The more stressed the user is, the faster the heart rate, and will light up a different LED as well as play the corresponding sound. There are 3 different levels of stress depending on the user's BPM, which correspond with 3 different LED's, green for low, yellow for medium, and red for high.

 Midterm Project Progress 10/14/24 Wired LED's, speaker, and microcontroller to breadboard. We haven't gotten the heart rate monitor yet but have everything prepared to connect it.
