Hi All ,
Looking for some help with my code please .
What I Want It To Do :
Nano powers up
4 LEDs fade in
1 red LED stays at full brightness for 2 seconds
3 LEDs pulse dim to bright randomly for 2 seconds after fade in
All LEDs fade out
A blue LED fades in
Blue LED stays at full brightness for 2 seconds
Blue LED fades out
Sketch loops again until power is turned off
What It Does :
Nano powers up
4 LEDs fade in
1 red LED stays at full brightness for 2 seconds
*Here is the problem *
The 3 LEDs pulse randomly until they reach full brightness then they stay on for 2 seconds instead of pulsing dim to bright randomly for 2 seconds after fade in
Everything after the above step does what is expected
All LEDs fade out
A blue LED fades in
Blue LED stays at full brightness for 2 seconds
Blue LED fades to black
Code loops again until power is turned off
I think the problem is the “ if ( ledLevel == 255 ) “ but I don’t know what to do to separate the pulsing LEDs from the static blue and red LEDs .
Code attached below , thanks for reading ,
Tom
