Multiple physical buttons GPIO - only one push button at a time + RGB strip and relays sequence with variable delays

General
1

Hi,
My project is simple for now:
I have 3 physical buttons which I connected to my relay board. Each button is connected to a separate relay and what node can I use to prevent simultaneous pressing of two or three buttons at the same time. I am looking the whole web to do so but there are all topics with one button or multiple presses on a single button.
I want to make the whole sequences for each buttons with relays but for know I must know how to push only one button at the same time.
I think the function node will be helpful for that but I don't know javascript language.

I will be very grateful for your help

I'm guessing the physical buttons "lock" when pressed.
So you press it, and it stays in a condition.
You press it again and the condition toggles.

I don't know if that will be easy.

You may need to go to press buttons (momentary press, non-locking).

Then you will have to make a bit of code.
Each button sets a topic for its message.

All 3 messages are sent into a node (function) and a lot of work happens in there.

Sorry, it is 21:11 local time and I woke up this morning at 05:45 local.
(Gotta love insomnia.) :frowning:

Here is a sample of how you could do it with the trigger node

Thank you Trying_to_learn and zenofmud.
I have Raspberry Pi4 and I want to use GPIO 3 physical push button to steer some sequences with relays. Each sequence will take 120 seconds. Now when I push button it doesn't "lock" when pressed is momentary.
So with trigger node I must prevent other buttons to activate other sequences for 120 seconds

@zenofmud has a good starting point.

I am new to NR 3.x

I don't want to step on his work, but I would do it slightly different.
Rather than the 4'th inject: a delay node set to 120 seconds and it sends the reset message.

Something like this:

No offense @zenofmud

6

I am sorry but I am beginner with node-red so it will be best to swap Reset node with delay node?

7

That is something you left out in your original post BUT it is easy enough to handle, just edit the trigger node and change it like this:

Screen Shot 2022-10-28 at 6.28.54 AM
Screen Shot 2022-10-28 at 6.28.54 AM506Ă—625 36.1 KB

and you can get rid of the 'Reset' button

[EDIT] changed the then send to nothing

8

(Sorry again)

But neither of the flows allow toggling of the output.

But that could be handled after the switch node with a function node that toggles.

9

@aquapark_lodz do you want all 3 buttons disabled for 120 seconds though?

So you press a button and can't press another for 120 seconds?

Or just don't want more than one pressed at any one time?

10

My original image needed a change

11

Here's a very quick modification of the flow created by @zenofmud
Once a button has been clicked, the delay is triggered so further clicks are ignored until 'msg.reset'.

I setup trigger for 5 seconds to test it but with trigger node on the startup it's only delay time for 5 seconds from push button to working rest of the code.

My goal is as follow:
we have 3 physical buttons:
Yellow button - to start some sequence with relays - working time 120 seconds
Blue button - to start some sequence with relays - working time 120 seconds
Red button - to start some sequence with relays - working time 120 seconds

When I push for example blue button and start some sequence for 120 seconds I want to prevent to push other buttons to start yellow button and red button sequence when blue button sequence is working at the moment. when the sequence is over I can again choice which of 3 sequences I can use

13

please export your flow and attach it to a response and I'll take a look.

(That's what mine did) :wink:

So it does - just imported your flow.

The problem with the flow as is, that the relay/s will never be turned off.

You need to do just a bit more between the switch node and the GPIO-OUT node.

Basically you need a function node to receive the message and toggle what is sent to the GPIO pin.

One on each of the outputs.

(code in the function node as best I can make it just now)

let x = context.get("state") || 0;

x = (x + 1)%2;
context.set("state",x);

msg.payload = x;
return msg;
17

Great minds think alike.

(Or is it: fools seldom differ?)
:wink:

You can see that I want to make sequences for each buttons: for example when I push blue button the sequence starts: 10 seconds to open relay number 1, 2, and then relay 1, 2 close and relay number 5, 7 open for 15 seconds, and then relay number 10, 11 open for specific time. I have to think also to add rgb light to this and sound. So it will be the whole sequence for one button during 120 seconds.

my code is below
