I am going to create a project with a friend, but I have some technical questions.
The Arduino Nano has an EEPROM capable of storing the known WiFi connections. Basically what I want is say "Arduino, connect to this WiFi and remember it". When I then disconnect the Arduino completely, it should still save that information. Can the EEPROM store that without power?
I need an easy, but rather small, WiFi module to work with the Arduino Nano. I've looked at the ESP8266. I don't mind soldering the ESP8266 to the Arduino Nano once, but doing it more times (perhaps because I need more GPIO or something) is not a variable solution. If I get the ESP8266 ESP-12, I would only have to solder it to the Nano once. However:
- Is the ESP8266 ESP-12 compatible with the Arduino Nano?
- I like the ESP-05 because it's small and simple. Would that work?
Are there perhaps better ways of doing this whole thing? Should I go for something else than the Arduino Nano? I need to hook up:
- Microphone (smallest and easiest way)
