I was wondering if theres any way I can make my Arduino waterproof. I don't want to use a lunch box or something similar because I'd like to keep my project as slim as possible.
I've read about something called "potting compound". Will this keep my Arduino dry in lets say a washing machine? :)
What about silicone? Would this work aswel?
Thanks for your answers!
In addition to the above answers, you need to have an enclosure of some type to contain the potting compound while it cures. You probably need to consider any external connections to the Arduino. Power? Data in and out? Wires will wick moisture into the Arduino board.
Way to avoid wires is to use a waterproof connector with the inside part of the connector also covered with the potting compound.
Potting compound is very thin so it can get to all parts of your project. Air bubbles are a problem, so you need to take care to pop any before the compound cures.
Most potting compounds have a limited lifetime, even in their original sealed, unused container. Many also have a minimum purchase quantity and in the US, will require a hazardous material charge for shipment.
