Can this be done with a state machine

[J-M-L]

@roelofw

Could the challenge be solved with a state machine or can I better use three for loops to make this work.

YES

For extra information and examples look at

• Using millis() for timing. A beginners guide
• Several things at the same time
• Flashing multiple LEDs at the same time

you might benefit from studying state machines. Here is a small introduction to the topic: Yet another Finite State Machine introduction
