Anyone know of any good articles on protecting Arduino and peripherals from the elements while outside?
do you require splashproof, stormproof, immersed in water, ?
if you search on Ebay etc waterproof enclosures have an IP rating
you then have the problem of getting power, data, antennas, etc connected
as soon as you start drilling holes you can have problems and require waterproof glands etc
how often do you require access? e.g. I have used these with a hinged lid in sheltered positions
also there may be other hazards - one of my collegues set up water level gauges on rivers in Africa - even though they used solid metal enclosures set in concrete the local hippopotamus would still wreck them
it depends on your needs
I usually use a clear Insulating Varnish Spray (look for PCB varnish) as it protects against corrosion, moisture, oxidation.. and you can also find waterproof project boxes, even with transparent cover if that makes sense for your project
That is a valid question! The general parts are Arduino,
64x32 RGB LED Matrix - 4mm pitch
Adafruit Matrix Portal - CircuitPython Powered Internet Display
Adafruit AirLift Shield - ESP32 WiFi Co-Processor
I am also planning on getting a 4g wireless modem to act as an internet connection for the WiFi co-processor board.
The location of this project will be in a public park. The whole goal of this project is to make an interactive Christmas Tree!
sounds like you require a IP65/66 waterproof steel enclosure with lockable hinged door
how will you power this device, e.g. mains, solar panel with battry, ?
what is the internet connection for? modems tend to be power hungry
Lucky enough, I have access to AC power, so power is not really an issue. The internet connection is how the tree will get data. The park does not have Wifi and the only thing I can figure is just do 4g.
what data does it require? how often? how much?
have you decided on a protocol and set up a server in the internet?
It requires a string input from a user. What it does, is takes a string value such as "Hello World" and iterates over each character and spells it out in Morse code. What I figure I can do is with the WiFi coprocessor issue a GET request to an API of a webserver, get the whole string, iterate over the string in the wifi co-processor and feed each letter to the Arduino, once the Arduino is done, the WiFi co-processor issues a POST request to the same API and then gets another string value.
Hopefully, this answers your question.
