This idea was first created in 2011 by two clueless students who had no idea on how to light up an LED, luckily however, after playing around with an Arduino Uno and learning some coding it seems like the idea can finally become a reality!
What is an Incentive Spirometer?
Briefly, an incentive spirometer is a medical device that helps strengthen the lungs. It is typically used after chemotherapy and before/after surgery. Basically, the user inhales through the mouthpiece and the piston rises and indicates the user how much air they have taken in. The user is typically given a goal amount of air they should be able to inhale, and therefore with each use the user tries to increase the air they have inhaled.The suggested use of the device is typically 10 breaths every 1-2 hours while awake.
Have any suggestions?

Using an incentive spirometer can be draining. Having to repeat the process repeatedly must not be any fun. Therefore, through the use of the attachment, we hope to make the process a bit more exciting and fun for the patient.
The attachment will consist of a graphic LCD screen, an infrared sensor, LEDs, a buzzer, and an Arduino Mini. Our end goal is to have the attachment monitor where the piston is located and then display that value to the user. Also, we hope to have the LEDs synchronized to this value and begin to blink faster as the user gets closer to their goal. The buzzer will also work in a similar way by playing a more upbeat song when the user is in the target range. As a result, we will need to make it possible for the user to change their target range. Also, since the user must not breath in too quickly, we hope to also be able to monitor the rate of change of the piston's location and tell the user if they are inhaling improperly.
We were basically inspired by the following carnival game~
