I am making project with Arduino NANO, Bluetooth module(RX and RT not yet connected), RTC DS3221 and a lot of RGB diodes.
I was not testing before soldering.
I am facing this bad readings on Serial monitor and don know why.
When I send these colors to the diodes they are also wrong. So something is wrong whit data in Arduino I think.
About Serial, I made a mistake and used wrong baut, when I put it to 9600 it worked.
About diodes, It changes this values in this part of code. Based on what it gets from Bluetooth. And while RX and RT are not connected yet and I am not sending anything on Bluetooth, it still change values. When I put // it worked fine.
