The simplest embedded system used in real life is car parking system. So what's the most important thing need to be taken care of in a parking lot? That's right! We need to make sure only as many cars get inside as the capacity of parking lot. So let's count how many cars pass thourgh a gate in a parking lot.

3. Whenever sensor on exist gate gets triggered Total number of cars is decreased by one.
4. Print total number of cars inside parking lot on terminal whenever a sensor is triggered.

Note: 2 IR Sensors will be provided for each team.

Submission Instructions

• Make a zip file containing
  (a) Your code file (main.c)
  (b) A video showing increment and decrement of total number of cars
