Hi i am brand new to Arduino and I have a project where i want to monitor the depth of the water in a time rate. It would then be able to responed to the lack of movement by alerting either though light or sound.
So for example: water is in a cup and you have taken a sip and then put it down. 10mins go past and the depth of the water is still at the same level so then the senor would pick up on that an alert the person to drink from that cup again.
i am just wondering if this possible and if so how this process uses the same sort of mechanisms in a smart washing machine which uses pressure sensors
