Humidifier Hacked with ATtiny to Auto-Press Buttons @Atmel
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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
