Time to look at these and modify your code in line with what you learn:

Blink without delay, which is in the examples in the IDE under digital.

Also study

Using millis for timing

Demonstration for several things at the same time

Finite state machine tutorial will also be useful

Timer counter state change toggle FSM - all at once

There is a recurring theme of people new to Arduino and/or microcontrollers not grasping the concept of putting what I call ‘building blocks’ of code together to achieve some goal. These short sketches are an attempt to offer some examples showing how small pieces can be used in concert to build up larger, more complex sketches. Thanks to @PerryBebbington and @ballscrewbob for support and input. You made it better. The examples will illustrate: • Doing ‘several things at once’ • pitfalls of …
