After some research I´ve found two main tutorials: 1) He explains everything so well i felt like I could even understand it (but he used the library that they are saying isn´t very good (but I´ve managed to make the RTC work perfectly with this one) here´s the link to the youtube video with all the info in the description box:
The thing is he used a normal LED and I want to use an RGB one to resemble the sun better SO i found this other tutorial that uses the adafruit neopixel (I got the 12 led ring)
The goal now is to mix both codes to be able to use it with the RGB led. Do you think it´d be too difficult to include the adafruit library/code (i dont really know the difference lol) into the first simpler code?
And this is how everything would be wired:
But I dont know if I´d need to put on some resistors or if to power it´d be enough through the USB or a 12V transformer to the arduino or breadboard power supply. (I know I´m asking wayyyy too much so if you don´t really know how to help is completely understandable!)
And thanks for the tip on how to post code
