John F Kennedy Catholic School – Years 12-13
The COVID-19 pandemic has dramatically increased rates of anxiety, so we wanted to create a heart rate monitor that could make people aware of a possible anxiety attack early enough for them to do something about it.
To get out heart rate sensor to work, we started with example code from the internet before calibrating it for our hardware. We wanted to give people a simple way to relax if an anxiety attack was imminent, so we built four simple games into the device: paint, snake, a number guesser and blackjack. We then added a basic menu so people could navigate between the heart rate monitor and the games.
While making the games, we encountered a few problems. For example, while making the blackjack game, we found everything would happen at once, without a pause. This meant the display would suddenly become crowded and hard to read. We fixed this by adding a variable called “Continue?”, which pauses the program as cards are dealt, allowing the user to proceed when they’re ready.
This is a simple device with low cost, giving it potential for mass production to help numerous people reduce anxiety attacks.
