How do you stop a 7 segment display by a push button?

chibbs · April 7, 2022, 4:56pm

Hi. I'm currently a student studying robotics cause its required for my school. I have an assignment about making a buzzer beater. Like the ones on shows where there's a limited time and the players have to press a button where the buzzer will make a loud noise and stop the timer. Well I had tried to make one in Tinkercad with such little notes my teacher gave me and it's not really working out for me. I was hoping someone could help me out cause its deadline is near. Also I'm really new to coding and robotics so pls be nice cuz i really dont know what im doing.

Statement like delay(1000) mean "do nothing for 1 second". That means you can't read a button.

Study this tutorial to learn how to avoid using delay(): https://www.baldengineer.com/blink-without-delay-explained.html

This looks quite a bit like this thread. Seven segment display with one pushbutton on arduino uno - #6 by Programmer0009

Programmer0009 · April 7, 2022, 5:04pm

it is but my code also doesn't work. I'm stuck in a last(one) step.

Programmer0009 · April 7, 2022, 5:07pm

did you try with a input_pullup

chibbs · April 7, 2022, 7:36pm

How do you do that?

How do you stop a 7 segment display by a push button?

Fit a shot gun cartridge underneath the display. Arrange that a hammer swings on a thread and hit the cartridge on the ignition point. Have the thread holding back the hammer cut when a solenoid with a scalpel blade on it is fired.

Then wire that solenoid to a logic level FET to an output pin. Detect the logic level of a switch and let that trigger a pulse on the output connected to the solenoid. It works very good but only once.

Alternately you can use an if statement to see if the time is up and when it is turn the sound on.
Tip never use the exit command anywhere it is a sign that you haven't got a clue about how to program and you wouldn't want to give that impression would you?

So if the loop is terminated because PUSHBTN1 is equal to 1 how are the instructions that follow it ever going to be executed? Not even the else will be reached because that exit stops anything else happening.

usually studying is done after school at a university
If you have left school and started studying.

The most important thing to learn is to become independent of the professors "teaching" which is often not teaching but read out.

The basic thing is to learn how to do independent completion of projects.

This includes asking experts (other experts than the professors)

You seem to have underestimated how much time it needs to learn programming
or other possability you have been lazy about working on this project.

Your code needs to count-down until the button is pressed.
Then the count-down shall stop and the buzzer shall be turned on
which means change from executing count-down to execute buzzing.

Be the change you want to see in the world

Hi Stefan. Thanks for the comment and trying to help me but I'm still having some trouble. I know it's stupid and I am really stupid for this subject so I'm sorry if you get disappointed for the result. I tried someone's advice to make the timer play. It eventually did but my problem now is the button. I also tried the demonstration code you gave me. Um it did not work for me. I probably did it wrong and put just stuff that did not make sense. The 7 segment display is just not working and I'm really confused. I didn't get a good foundation on what are functions and stuff, I just followed my teacher's code that's literally all I learned. Not blaming it on them though, I need to study more of this. But if you could give me some advice, that would be great. Here is the code I made where the timer works.

Also, I'm really grateful for you helping me. I'm sorry if it feels like your teaching me without me paying you. But if you can't help me with this, it's all good either way.

StefanL38 · April 9, 2022, 8:54pm

I don't believe you if you say

It took you

two days

to answer.

To be more precise:
Your code needs to count-down until the button is pressed.

if button is not pressed simply count-down.

If button is pressed
Then the count-down shall stop

and the buzzer shall be turned on
which means change from executing count-down

to execute buzzing.

There is no way around learning the basics.
If you want to keep my support. You should answer quickly with a question about a detail.
Regardless what the detail is. You seem to try to finish this at highest-speed in the last second. This does not work.

You should change to learn at highest intensity = asking dozens of questions about the details.

Take a look into this tutorial:

Arduino Programming Course

It is easy to understand and has a good mixture between explaining important concepts and example-codes to get you going. So give it a try and report your opinion about this tutorial.

Be the change you want to see in the world

Why are you ignoring my post #8? The exit call is just screwing you up.
As soon as you use it the function ends and the instructions following can NOT be run.

chibbs · April 9, 2022, 9:08pm

Yes yes I knew what you were talking about. I was just trying to figure out how to stop the timer. I wasn't trying to ignore your post. I'm sorry if you saw it that way. Also I took your note about the exit call, I was just trying to show the code for the timer.

chibbs · April 9, 2022, 9:16pm

I'm sorry if I took two days to answer. I had family matters and my teacher changed the deadline because too many students were complaining about the deadline. I'm also sorry if I don't understand the concept of this subject. I'm a literal teen learning this subject with minimal notes about the basics. I was taught to just copy what the teacher gave me, and if you think I'm making excuses for "not studying" the basics and me being "lazy" about this project, I'm being full honest here so I could finish my project on time. Thank you for your help but I'm sorry if I'm too busy to even reply to you faster than you want. It's midnight and I am struggling right now.

StefanL38 · April 9, 2022, 9:18pm

So this answer did explain a little bit about your situation.

when

will you post a question about a detail?
This evening?
or do you want to go to bed now and post the questions
5-6 hours later?

chibbs · April 9, 2022, 9:24pm

5-6 hours later. I'm sorry if this makes you feel unhappy or disappointed that "I'm not learning" or I'm not trying my best but I am trying and just trying to pass this project on time. It's due on April 18 so feel free to not even help me anymore if you're just gonna tell me I'm lazy about this project.

StefanL38 · April 9, 2022, 9:26pm

until April 18 is 8 days. Caclulated from tomorrow until 17 april.
How much time can you afford each day learning programming?

chibbs · April 9, 2022, 9:29pm

3-5 hours maybe. I do house chores everyday and I have 3 projects due on Monday and Tuesday.

StefanL38 · April 9, 2022, 9:32pm

3-5 hours per day or in summary?
