HI everyone, so i have this code and it works if i just use delays. The application is for a drinks machine controlled via bluetooth on the phone fyi. But the issue is when I tried to use blink without delay instead the pump doesnt come on, and the code seems to just bypass the interval period for t…

A millis-timer is used this way: Start the millis-timer and then continue with the sketch. The millis-timer runs on its own in the main level of the loop(). That means you need two pieces of code. One piece of code that starts the millis-timer and then the code for the millis-timer itself. They b…

YEs a "state mechine" may make the process easier to code. Have a look at my tutorial here [image] Beginners: using the switch - case statement Introductory Tutorials The switch - case statement is a powerful construct that is often under-used by beginners. Basically it …

Right thank you both for your replies, it will have a few steps so I will look into the state machines.

This may help too: [image] Why add a flag to Blink Without Delay (BWD) ? Introductory Tutorials Newcomers to Arduino, soon discover the usefulness of using the Blink Without Delay (BWD) technique for timing events. As most old timers realize, adding a Flag to this techni…

A drink machine is a typical Finite State Machine sketch. It will be worth your time to learn to use it. The tutorial by @johnerrington is good. My style of coding is slightly different, you can find a few examples on my Fun With Millis page (look for the word 'finite') and test them directly in Wo…

Ive just haf a quick look at the tutorial by johnerrington, but with this do all the values need to be stored in an array, because I am sending them over bluetooth?

@Koepel I love the idea of this sketch, I'll have to try it. Koepel/Fun_with_millis/blob/master/millis_overdone.ino // --------------------------------------------- // millis_overdone.ino // --------------------------------------------- // License: The Unlicense, Public Domain. // Au…

[image] Koepel: Start the millis-timer and then continue with the sketch. Always worth reminding, though we presume the OP here understands, that "starting the timer" does not mean interfering with the timer system in any way, but recording the immediate value of millis() for later compariso…
