Good day,
I have issue with my sketch, the sketch is for a radio controlled robot which I wish to had addressable individual LED strip.
The remote control has two thumb joystick, joystick 1 is to turn on/off lights when pressed, joystick 2 is to cycle through LED patterns when pressed.
Problem : ELse if doesn’t seem to work, once it goes through the first else if the serial monitor display 255. I treid removing 2 Else IF and it behaved differently.
-
How to fix else if?
-
I have tried to see how to clear led so next mode can have correct LED lit but I am unable to figure this as well, I have tried FastLED.clear(); but seem to not do anything.
thank you in advance.
this is a sketch I am testing with to figure out things.
