Medicine Delivery System
The only keys used are a,b, and c. a controls switch 1, b controls switch 2, and c controls switch 3. Each switch represents one risk factor for a patient, meaning a value of 0 means the risk factor is not present, and a value of 1 means it is. A green light means no risk factors, yellow 1, red 2, and a cat's meow means 3. The medicine system will change the light based on the switch values every 5 seconds.
NOTE: The switching of the variable is really, really laggy. You have to play around with the a, b, and c keys to actually get it to change the switch from on to off and vice versa.
