Stories like this are great – especially when they involve a tech solution for cheese-making! These simple humidifiers have the ‘feature’ (it’s not a bug!) of needing to auto-press a physical button to cycle between 4 modes before initiating, whereas the user wanted the controller to simply activate the humidifier when needed. Solution? Program an ATtiny to simulate the button-pressing, letting the controller do its job. Brilliant!
A friend who’s into cheese making needs to control the humidity of a fridge which he’s transformed into a cheese cave (I think the fridge itself is a wine cellar and has integrated temperature control).
However, he was having a “silly” problem: all of the humidifiers did not start automatically when plugged in (which is what the controller was effectively doing) but had at least 1 button to be pressed first.
In steps the ATtiny – problem solved!
