How can I modify the state machine logic?
Hi @Marvee Amasi to prevent the invalid transition from CoinInserted to Dispensing when the selection hasn't been made yet, you can modify the state machine logic to introduce an intermediate state between CoinInserted and SelectionMade. your code for the VendingMachineState enum should be 
typedef enum {
  STATE_IDLE,
  STATE_COIN_INSERTED,
  STATE_SELECTION_IN_PROGRESS,
  STATE_SELECTION_MADE,
  STATE_DISPENSING
} VendingMachineState;
typedef enum {
  STATE_IDLE,
  STATE_COIN_INSERTED,
  STATE_SELECTION_IN_PROGRESS,
  STATE_SELECTION_MADE,
  STATE_DISPENSING
} VendingMachineState;
