 # Slush-Refiller
 
 Automatic refiller for the slushice machine basing on a peristaltic pump.
+
+It uses an input pin to detect the fill level of the Elmeco slush ice machine. The elmeco machine has two metal pins to measure the fill level. We re-utilise these pins.
+
+The Slushice-Refiller is a modified cap of a 10l DIN tank, such that it can be placed on top of the tank instead of the original cap. It runs on 5V DC, so that it can be powered with a standard USB charger or power bank.
