Good afternoon all,
I am new to this so apologies in advance if this is something quite simple. I have a Mega2560 and have in the past used it for lighting up LED strands (white Christmas lights).
I have decided to use RGB LED lights for 2018 and I tried the colour palette sketch from the library which worked fine. I was given a code to try as a simple trial to enable me to get used to the Arduino coding. I loaded the code and it appeared to work and then the second time it only lit up 10 of the 50 RGB nodes sequentially and they then started to flicker.
I have subsequently tried load various sketch codes which have worked previously and I keep having the same error message appear: please see below.
I would appreciate any advice or guidance. Many thanks in advance. Mark
