Find & Fix

As a Find & Fix project, I made an indicator. I found the problem that sometimes there is no water and no person to change an empty bottle of water in the right hall at ITP because all bottles of water are in man's room. Therefore, this is the prototype.
Actually, It is supposed to be drained little by little away but because I couldn't make a water cooler, I will pour some water into a cup to measure how much water left in a bottle.

Led is supposed to be blinked when there is no water in a cup to indicate no water and to encourage to change a bottle.


For more pressure, I put a this kind of shape of wood block on a pressure sensor.


To measure how much water left in a bottle, I used a seven segment. From 4 to 0 the number of sign will be shown.
