He won’t drink from a bowl. So we want to use LittleBits to open a solenoid valve that I can put in under the sink. Hopefully I can find a 12V solenoid so I can power both the solenoid and LittleBits from the same power supply… I’m sure I can find a 24V solenoid. I won’t use a 120VAC solenoid.
I don’t want to even think about trying to train a cat to press a button. We should be able to use the Motion Sensor Bit. Does anyone have any experience with it’s range? If it’s not much then maybe it’s likely to get wet. What’s the best way to seal it? Silicone? Spray paint or varnish?
The 5V and 250ma from LittleBits is not enough to operate a solenoid. It’s not clear online if the Proto Bit will pass thru a different voltage other than the 5V control voltage from LittleBits, i.e. 12V. The website is also not clear how to wire the Proto Bit to power the solenoid or a relay. Does anyone know how to connect LittleBits to a solenoid?
Does anyone have any better ideas?
