Hi,

One of my friend asked me to design a Water control unit for him.
It has to be able to:
- identify the water levein the boiler through the sight glass
- able to reduce the effect of the air bubbles and the water bouncing
- control a servo wich is able to open or close the mechanical water pump
- control an electric water pump as an option
- able to measure the feeder tank water level
- should have a signaling option, like an Alert Led
