I think he is trying to show us that we can use pwm signals and gnd from two different Arduinos. For this circuit it would work for both LEDs together or for none. Single Led cannot be controlled unless both Arduinos share common ground. This can be used for asynchronous applications but at the end it is no different than using two separate Arduinos.😂
This is the link to the GitHub repo. Download this repository. you will find FirebaseArduino.h in the SRC folder. Copy and Paste the file in Arduino/Libraries.
Best of Luck!
There isn't a video on wiring. If you are not able to understand the wiring on breadboard then just follow the color of the wires. For eg. The green wire with breakage in the schematic can be considered as one wire. This should help.
Best of luck!
