Button... Controll Menu Question

[Jordy101091]

Hi all,

Im working on my rewrite of my aquarium controller, Im currently working on the menu and want to use one button for entering and exiting from the menu.
I want to do this by using a short press to go to the next item of the menu and a longer press (2sec) to exit the menu.

I dont know how to go around this, maybe you can help.

Regards Jordy

Hi Jordy,

There are a few ways of doing this.
Attached is what I believe is the simplest way using one button.
There may be other ways of course.

I could create a flowchart using several buttons, but will be more complex

Flowchart will also eliminate issues caused by contact bounce.

I have added 2 more switches.
So now you can short press or long press any combination simultaneously.
I have mapped switches with keys 0 to 2.
so
Key 0 will control switch connected to A0
Key 1 will control switch connected to A1
and Key 2 will control switch connected to A2
You can also have a combination as stated earlier.
E.g press keys 0 and 1 and keep held for a second for long press A0 & A1
or press keys 1 and 2 and release key 2 for short press A1 and long press A2 etc.
So now you can have 24 menus from just 3 switches (if I have worked it out correctly, prob not )

This version works much better on hardware with more than one switch pressed simultaneously.
