Without babbling on here is my plan: I want to put a led light string inside of an rc plane and have an ”aurdino nano” control them and create a fire effect. I am not into programming really but I feel like I can achieve this, however it would be cool if I could have an on off switch for the data wire to the LED’s that I could control with the planes transmitter (remote), because turning the aurdino on and off would be too slow. Can an on off switch (not for the aurdino) be implemented fairly easy? (I will be using theese LED’s: https://www.ebay.com/itm/50X-12mm-LED-Module-RGB-WS2811-Digital-Pixel-Addressable-ledrip-waterproof-E5N2/282779684162?pageci=9edb201f-2c88-4fd0-8ae9-34c54e2e6a28&epid=2074447882
As the output from the planes Rx is a Modulated pulse signal , it might easier to use that as another input to the NANO and switch an output of the nano corresponding to that . You can then switch a transistor to turn the lights on and off.
so I do somethig like: if one input of the nano activates, then it activates the output and the LED control operation?
