Customer:
I purchased two Croduino NOVA boards about a year ago but haven’t had a chance to test them until now. I’m looking for a simple example program for connecting two Croduino NOVA boards - for instance, a button on one board that turns an LED on and off on the other board.

prije godinu dana sam kupio dvije CRODUINO NOVA pločice, ali nisam stigao prije isprobati pa je sada došla na red,
Zanima me dali imate neki jednostavni primjer program povezivanja dvije CRODUINO NOVA pločice npr na jednoj CRODUINO NOVA jedno tipkalo koje pali i gasi na drugoj CRODUINO NOVA jednu led diodu.
hvala

You can achieve this in several ways. One approach is using a local network where one Croduino NOVA acts as a server and the other as a client, connecting to it to control the LED. Another method is over the internet without a local network - you would need an internet server to store a variable that indicates whether the LED should be on or off. For example, data.sparkfun.com. The internet approach is probably simpler to implement since everything is already set up, whereas with the local network method you need to configure everything yourself. Unfortunately I don’t have a finished example in Croatian, but here’s one in English for the local network approach: How to Make Two ESP8266 Talk with each other | Random Nerd Tutorials

You can also look at examples using data.sparkfun.com - it’s simple and effective (instructions are available on the home page).

ovo možete napraviti na više načina. Recimo da se radi o lokalnoj mreži, jedna Croduino NOVA bi se ponašala kao server, dok bi druga bila client, povezivala se na nju te palila/gasila LED diodu na njoj.
Drugi način je preko interneta, dakle ne na lokalnoj mreži, tu biste trebali neki server na internetu koji bi spremao/čuvao varijablu koja bi značila paljenje ili gašenje LEDice. Npr. data.sparkfun.com
Drugi način je vjerojatno jednostavniji za napraviti jer je sve već postavljeno. U prvom načinu Vi sve morate postaviti i konfigurirati. Nažalost gotov primjer nemam na hrv jeziku, ali šaljem Vam na ENG za prvi način:How to Make Two ESP8266 Talk with each other | Random Nerd Tutorials

Možete također pogledati primjer korištenja data.sparkfun.com, jednostavno je i efikasno(odmah na home stranici se nalaze upute za korištenje).
