| + | * The led bar is formed by 10 parallel leds. | ||

| + | * For this project only 4 leds were used to offer a visual representation of the water lever, the more leds are turned on, the higher the water level is. | ||

| - | * Of course there are intermediary stages for the LEDs based on the level of the water which will attract more or less the user to drink the water. | ||
