You need to design a vending machine controller that should exhibit the following behavior:

$$ The vending machine delivers a package of gum after it has received $15$ cents in coins.

$$ The machine has a single coin slot that accepts only nickels $(5$cents$)$ and dimes $(10$cents$),$ one coin at a time.

$$ A sensor indicates to the controller whether a nickel or dime has been inserted in the coin slot.

$$ The controller$$s output causes a single package of gum to be released when it has received at least $15$ cents, and the controller is reset.

$$ The machine does not give change. For example, if two dimes are inserted, it will release the gum and reset. Write the embedded C code to implement the same
