                                        "COUNTER FROM 0 TO 999"

The counter system main components are:

1. Tiva C board
2. LCD
3. 3 push buttons (increment by 1, decrement by 1, reset to 000)
4. Battery to power all components
5. Power switch (on/off) to enable/disable power of the entire system including Tiva C

The operation mode of push buttons:

1. Increment : While pressing
2. Decrement : On press event
3. Reset : On release event

The concept of this system can be used in many applications.For example, it can be used to count number of people in queue if we replace . the increment and decrement push buttons with two photo interrupters and based on the number of people in the queue estimate the waiting time for a new person who is going to stand in the queue.
